                                  THE COMPANY
 
INTRODUCTION
 
     IOMED, Inc. (the "Company") develops, manufactures and commercializes
controllable drug delivery systems using iontophoretic technology. Iontophoresis
is a non-invasive method of enhancing and controlling the transport of
water-soluble ionic drugs into and through the skin using a low level electrical
current. The Company's proprietary iontophoretic drug delivery systems allow
rapid onset and cessation of therapeutic action, as well as programmable dose
control. The systems enable caregivers to monitor and control the onset of drug
effectiveness and maintain, reduce or cease drug administration once a desired
therapeutic effect is observed. Additionally, the Company is developing systems
designed to permit patient control and selfadministration. The programming
feature also enables caregivers to customize dosing patterns to meet each
patient's specific needs. The flexibility of the Company's proprietary systems
provides therapeutic control not possible with many alternative drug delivery
methods, including oral tablets and capsules, injections, inhalants, and passive
transdermal patches. The Company's systems may also increase bioavailability,
safety and patient comfort.
 
BUSINESS STRATEGY
 
     The Company's primary business goal is to establish its proprietary
iontophoretic drug delivery systems as a cost effective preferred means of
delivering a wide range of drugs. The Company's strategy for achieving this goal
includes (i) pursuing product development of drug delivery systems for
off-patent drugs with known safety and efficacy; (ii) entering into
collaborative relationships with pharmaceutical companies for the delivery of
new chemical entities and proprietary drugs; (iii) broadening the market
penetration and potential applications of the Company's existing delivery
systems; (iv) enhancing the Company's technology platform through internal
research and development; (v) pursuing new technology through in-licensing and
acquisitions; and (vi) retaining control of the manufacturing revenue stream.
 
COMPANY PRODUCTS
 
     The Company currently markets two products, an iontophoretic system used to
deliver dexamethasone sodium phosphate ("Dexamethasone"), a corticosteriod used
in the treatment of acute local inflammation, and an iontophoretic system used
to deliver Iontocaine, a proprietary drug used for local dermal anesthesia. The
iontophoretic drug delivery systems the Company currently markets are comprised
of a reusable programmable dose controller which is used to direct the
electrical current to control drug dosing and a pair of proprietary disposable
electrodes, one containing the drug and one serving as a grounding electrode to
complete the electrical circuit through the skin. The drug delivery electrode
may be applied to the patient's skin at a local treatment site (such as for
joint or tendon soreness or to induce local dermal anesthesia), or at any
suitable site on the body for systemic drug delivery. When an electrical current
with the same positive or negative electric charge as the drug is applied to the
drug electrode, the drug is repelled from the electrode and into and through the
skin.
 
     Dexamethasone. The Company's acute local inflammation product is a system
used principally by physical therapists and professional athletic trainers for
the delivery of Dexamethasone. Since it was
 
                                        3
<PAGE>   5
 
introduced in 1979, the Company's product has been used in over 10 million
patient applications for the treatment of acute inflammatory conditions such as
tendonitis (e.g. tennis elbow, golfers elbow and achilles tendonitis), bursitis
and carpal tunnel syndrome. More than 8 million of these applications have
occurred since 1990, when the Company introduced its present family of gel
electrodes for use with its microprocessor controlled dose controller. The
product is currently marketed to the physical therapy market as a device, under
a 510(k) pre-market notification by the United States Food and Drug
Administration ("FDA"), for use in connection with delivering ions of soluble
salts or other drugs. Recently, the FDA determined that all future iontophoretic
drug delivery systems will be required to go through the New Drug Application
process with the specific drug that is to be delivered. In order to address the
new regulatory framework and to broaden the clinical basis for the treatment of
acute local inflammation using the Company's iontophoretic delivery system for
Dexamethasone, the Company has filed an Investigational New Drug application
with the FDA and has initiated clinical studies to establish formally the safety
and efficacy of its drug delivery system for Dexamethasone. If the clinical
trials are successful and the Company receives regulatory approval, the Company
believes it will be able to actively promote the iontophoretic delivery of
Dexamethasone to general and family practice physicians, orthopedists,
neurologists and sports and industrial medicine clinics. The Company believes
the ability to promote iontophoresis with Dexamethasone will enhance its ability
to establish its delivery system for Dexamethasone as a primary treatment option
for acute local inflammatory conditions.
 
   
     Iontocaine. The Company's iontophoretic delivery system was approved by the
FDA in January 1996 for use in inducing local dermal anesthesia, and the Company
began marketing the product in early 1997. Iontocaine is the first drug with
labeling specifically for iontophoretic delivery. In addition, Iontocaine is
approved for use only with the Company's drug delivery systems. The Iontocaine
product provides needle-free, long lasting local dermal anesthesia up to six
times more rapidly and up to three times deeper than can be achieved using
topical anesthetic creams. The Company is initially marketing its Iontocaine
delivery system under the name Numby Stuff to pediatric hospitals in the United
States for use in connection with inducing local dermal anesthesia prior to
pediatric intravenous starts, blood draws, lumbar punctures and other similar
invasive procedures. At the Company's request, Numby Stuff was recently reviewed
by the new product review committee of the Alliance of Children's Hospitals
("ACH"), a consortium of 36 free standing children's hospitals in the United
States. Following the review, the Company acquired a right from ACH to use the
ACH Seal of Acceptance in connection with the commercialization of Numby Stuff.
In order to use the Seal of Acceptance to promote Numby Stuff, the Company was
required to make royalty payments to ACH. The Company satisfied ACH's royalty
requirement by issuing ACH warrants to acquire 44,791 Common Shares. In
addition, in connection with obtaining the right to use the ACH Seal of
Acceptance, the Company sold an ACH affiliate 37,202 Common Shares. The Company
plans to extend its marketing efforts for Iontocaine to include pediatric
clinics, non-pediatric hospitals, and office based physician practices for use
in connection with numerous therapeutic applications, including blood draws and
minor dermatological procedures. The Company is also evaluating the use of
Iontocaine in connection with gynecological procedures requiring dermal or
mucosal anesthesia. The use of Iontocaine for mucosal applications will require
additional FDA approval.
    
 
     Many pharmaceutical compounds, including peptides and oligonucleotides,
have physical and chemical properties consistent with delivery by iontophoresis.
Therefore, the Company believes its technology may be applicable to a number of
other compounds and therapeutic applications. The Company is also independently
developing a number of iontophoretic drug delivery systems for other
indications, including conscious sedation, tocolysis (the remission of pre-term
labor), and postoperative and chronic pain control.
 
COLLABORATIVE RELATIONSHIPS
 
     Novartis. In July 1995, the Company entered into a research and development
agreement with Ciba Pharmaceuticals Corporation, a predecessor to Novartis
Pharmaceuticals Corporation ("Novartis"), an affiliate of Novartis Pharma, A.G.,
the international pharmaceutical company formed as a result of the merger of
Ciba-Geigy Corporation and Sandoz Corporation in 1997. The collaboration was
formed to evaluate the development of iontophoretic drug delivery systems for a
number of Novartis compounds for use in several
 
                                        4
<PAGE>   6
 
therapeutic applications. The joint effort is currently directed toward the
development of a delivery system for a compound to treat osteoporosis. The
Company believes this system could enter Phase I clinical trials during 1998.
 
     In connection with the collaboration, Novartis purchased a 20% equity
interest in Dermion, Inc. ("Dermion"), a subsidiary of the Company that conducts
most of its research and development activities. The Company, Dermion and
Novartis amended the terms of their collaborative arrangement. Under the terms
of the amendment, effective November 1, 1997, Novartis exchanged its interest in
Dermion for 238,541 Common Shares of the Company and warrants to acquire under
certain conditions and through November 1, 2002, an additional 18,750 Common
Shares at an exercise price of $21.60 per share. As a result, Dermion became a
wholly-owned subsidiary of the Company. Pursuant to the agreements, Novartis is
required to pay for research costs under the program and to make milestone
payments upon the successful completion of certain later stage development
objectives. In addition, the Company granted Novartis a perpetual,
non-exclusive, royalty bearing license to the Company's iontophoretic technology
as well as certain rights with respect to future technology developed or
acquired by the Company.
 
     Elan. In March 1997, the Company entered into agreements with Elan
Corporation, plc and certain of its affiliates (collectively, "Elan"), an
international developer and manufacturer of advanced drug delivery technologies.
The agreements provide the Company with exclusive, worldwide licenses to certain
of Elan's iontophoretic drug delivery technology, including over 250 issued and
47 pending United States and foreign patents, as well as a significant body of
know-how and clinical study results. The Company believes the Elan technology
significantly expands its iontophoretic technology platform, enhances its
competitive position and better positions the Company to shorten the development
horizon of its iontophoretic drug delivery systems, including the miniaturized,
integrated, wearable systems currently under development by the Company. The
Company acquired the Elan technology by issuing two promissory notes, a $10.0
million note and a $5.0 million note (the "Elan Notes"). Under the agreement
with Elan, Elan will purchase directly from the Company, in private placement
transactions which will be completed concurrently with the closing of the
Offering, 833,333 Common Shares (subject to adjustment under certain
circumstances) for approximately $10.2 million and approximately $5.1 million of
Common Shares at a price per share equal to the initial public offering price
hereunder (425,000 shares assuming an initial public offering price of $12.00
per share) (collectively, the "Elan Shares"). Simultaneously with such
purchases, the Company will repay the Elan Notes, including interest thereon.
 
     The Company was incorporated in Utah in 1974 as Motion Control, Inc. In
1987, the Company merged with JMW Acquisition Corporation, and the name of the
merged entity was changed to IOMED, Inc. All references to the Company include
the Company's predecessor entities, as well as Dermion. The Company's principal
executive offices are located at 3385 West 1820 South, Salt Lake City, Utah

                                  RISK FACTORS
 
     IN ADDITION TO THE OTHER INFORMATION CONTAINED IN THIS PROSPECTUS,
PROSPECTIVE INVESTORS SHOULD CAREFULLY CONSIDER THE FOLLOWING FACTORS BEFORE
PURCHASING THE COMMON SHARES OFFERED HEREBY. PROSPECTIVE INVESTORS ARE CAUTIONED
THAT THE STATEMENTS IN THIS SECTION THAT ARE NOT DESCRIPTIONS OF HISTORICAL
FACTS MAY BE FORWARD-LOOKING STATEMENTS THAT ARE SUBJECT TO RISKS AND
UNCERTAINTIES. ACTUAL RESULTS COULD DIFFER MATERIALLY FROM THOSE CURRENTLY
ANTICIPATED DUE TO A NUMBER OF FACTORS, INCLUDING THOSE IDENTIFIED IN THIS
SECTION, "MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS," "BUSINESS" AND ELSEWHERE IN THIS PROSPECTUS.
 
     CONTINUING OPERATING LOSSES; UNCERTAINTY OF FUTURE PROFITABILITY. The
Company earned modest profits in each of the fiscal years 1988 through 1990, and
experienced losses from operations in fiscal years 1991 through 1995, due
primarily to increased investment in product development, clinical studies, and
increased sales and marketing activity. The Company again earned a profit from
operations in fiscal year 1996, but experienced a substantial loss from
operations in fiscal year 1997 primarily due to the write-off of purchased
in-process research and development. The Company had an accumulated deficit of
$21.6 million as of September 30, 1997. The Company intends to substantially
expand its research and development and marketing efforts in the near future
and, therefore, does not anticipate being profitable in the near term. The
Company's ability to achieve and sustain profitability will depend on its
ability to achieve market acceptance, and successfully expand sales of its
existing products, as well as successfully complete the development of, receive
regulatory approvals for, and successfully manufacture and market, its products
under development, as to which there can be no assurance. In addition, the
Company may be required to give away or substantially discount its current or
future products in order to stimulate demand, either of which events could have
a material adverse effect on the Company's business, financial condition and
results of operations. The success of the Company's current products and
products under development may also depend on the timing of new product
introductions by the Company relative to its competitors and other factors. As a
result of the foregoing, no assurance can be given that the Company will become
profitable on a sustained basis, if at all. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations."
 
     UNCERTAINTY OF MARKET ACCEPTANCE AND LIMITED MARKET PENETRATION. The
Company has generated only limited revenues, primarily from sales to physical
therapists of its drug delivery system for dexamethasone sodium phosphate
("Dexamethasone") for the treatment of acute local inflammation. The Company
began marketing Iontocaine, its proprietary local dermal anesthetic product, in
January 1997 and has generated only limited revenues from that product to date.
For the Company to be successful, its products will need to achieve broad market
acceptance by the medical profession. The Company's products use a method of
active transdermal drug delivery which, to date, has not gained significant
market penetration, and no assurance can be given that the Company's current or
future products will ever achieve broad market acceptance. Medical professionals
will not use or prescribe the Company's products unless they determine they are
a preferable alternative to products currently available on the market. The
Company believes recommendations and endorsements by influential medical
professionals may be essential for market acceptance of its products, but there
can be no assurance the Company will be able to obtain any such recommendations
or endorsements. In addition, the adoption of new pharmaceutical products is
greatly influenced by health care administrators, inclusion in hospital
formularies and reimbursement by third party payors. No assurance can be given
that health care administrators, hospitals or third party payors will accept the
Company's products on a large scale or on a timely basis, if at all, or that the
Company will be able to obtain labeling for its products which facilitate their
market acceptance or use. In addition, unanticipated side effects or unfavorable
publicity concerning any of the Company's products, or any other product
incorporating technology similar to that used in the Company's products, could
have an adverse effect on the Company's ability to commercialize its products or
achieve market acceptance. The occurrence of any such event could have a
material adverse effect on the Company's business, financial condition and
results of operations. See "Business -- Products and Products Under Development"
and "Business -- Sales and Distribution."
 
     UNCERTAINTIES RELATED TO PRODUCT DEVELOPMENT; CLINICAL TRIALS. Two of the
primary components of the Company's business strategy are to develop and
commercialize iontophoretic drug delivery systems for new and existing drugs and
to develop additional applications for its existing products. The Company will
be
 
                                        8
<PAGE>   10
 
required to undertake time-consuming and costly development activities and seek
regulatory approval for these new products and applications. Product revenues
may not be realized from the sale of any such products for several years, if at
all. The Company can give no assurance that its product development efforts,
either alone or in collaboration with other parties, will ever be successfully
completed, that it can obtain required regulatory approvals of its products,
that products under development can be manufactured at acceptable cost or with
appropriate quality, or that its products can be marketed successfully.
 
     Before seeking regulatory approval for the commercial sale of its products,
the Company must demonstrate through preclinical studies and clinical trials
that those products are safe and effective for use in the target indications.
The rate of completion of the Company's clinical trials is dependent upon, among
other things, the rate of patient enrollment. Patient enrollment is a function
of many factors, including the size of the patient population, the nature of the
protocol, the proximity of patients to clinical sites and the eligibility
criteria for the study. There can be no assurance the Company will be able to
obtain the patient enrollment it needs to complete its clinical trials in a
timely manner, if at all. The results the Company obtains from preclinical
studies and early clinical trials may not be indicative of results it will
obtain in large-scale testing, and there can be no assurance the Company's
clinical trials will demonstrate sufficient safety and efficacy for it to obtain
the requisite regulatory approvals, or that those clinical trials will result in
additional marketable products. Clinical trials are also often conducted with
patients having advanced stages of disease. During the course of treatment,
these patients can die, suffer undesired side effects or suffer other adverse
medical effects for reasons that may not be related to the pharmaceutical agent
or drug delivery system being tested, any of which can have an adverse effect on
clinical trial results. A number of companies in the pharmaceutical industry
have suffered significant setbacks in advanced clinical trials, even after
promising results in earlier trials, as a result of such adverse effects. The
use of any product the Company develops may produce undesirable side effects
that could result in the interruption, delay or suspension of clinical trials,
or the failure to obtain United States Food and Drug Administration ("FDA") or
other regulatory approval for targeted indications. If the Company's products
under development are not shown to be safe and effective in clinical trials, the
resulting delays in developing other compounds and conducting related
preclinical testing and clinical trials, as well as the need for additional
financing to complete such testing and trials, could have a material adverse
effect on the Company's business, financial condition and results of operations.
See "Business -- Products and Products Under Development,"
"Business -- Manufacturing" and "Business -- Government Regulation."
 
     RELIANCE ON COLLABORATIVE PARTNERS. The Company's strategy is to enter into
arrangements with corporate partners, licensors, licensees and other parties for
the development, clinical testing, manufacture, marketing or commercialization
of certain of its products or products in development. The Company currently has
a collaborative arrangement with Novartis Pharmaceuticals Corporation
("Novartis"), an affiliate of Novartis Pharma A.G., the international
pharmaceutical company formed as a result of the merger of Ciba-Geigy
Corporation and Sandoz Corporation in 1997. The collaboration was formed to
evaluate the potential for effective delivery by iontophoresis of several
Novartis compounds covering a range of therapeutic applications.
 
     Collaborative partners in the development of medical drugs and devices
generally have the right to pursue parallel development of other products which
may compete with the products of the other collaborative partner, and to
terminate their agreements without significant penalty under certain conditions.
Any parallel development by a collaborative partner of the Company of alternate
drug delivery systems, development by a partner rather than by the Company of
components of the delivery system, preclusion from entering into competitive
arrangements, failure to obtain timely regulatory approvals, premature
termination of an agreement, or a decision by a collaborative partner not to
devote sufficient resources to the development and commercialization of the
Company's products could have a material adverse effect on the Company's
business, financial condition or results of operations.
 
     The Company's success may depend upon, among other things, the skills,
experience and efforts of the Company's collaborative partners' employees who
are responsible for the collaborative project, such partners' commitment to the
arrangement, and the financial condition of such partners, all of which are
beyond the control of the Company. If one or more of the Company's collaborative
partners defaulted on their obligations
 
                                        9
<PAGE>   11
 
under their collaborative agreements, the Company could be forced to engage in
litigation to enforce those obligations (which could be time consuming and
costly) or seek to enter into agreements with other parties upon similar terms.
There can be no assurance the Company will be able to enforce the terms of its
collaborative arrangements through litigation, and there can be no assurance
that, if forced to terminate its current collaborative arrangements, the Company
would be able to enter into other contractual arrangements with other parties on
terms which would not be materially different from the terms of its current
collaborative arrangements.
 
     A significant portion of the Company's research and development resources
has been devoted to its contractual research and development efforts with
Novartis. Since 1995, Novartis has funded a substantial portion of the total
research and development costs of the Company. The amount and timing of
resources to be devoted by Novartis in accomplishing the objectives of its
collaborative development effort with the Company are not within the control of
the Company, and there can be no assurance that Novartis will continue its
collaborative development with the Company beyond the current term of the
agreement, which has been extended through December 31, 1998. Either party can
terminate the collaboration upon six months prior written notice. There also can
be no assurance that Novartis will perform its obligations as expected or that
it will not pursue other existing or alternative technologies in preference to
products it is developing with the Company or that it will not terminate the
collaboration prior to its expiration. In addition, in connection with this
collaboration, the Company granted Novartis a perpetual, non-exclusive, royalty
bearing license to the Company's iontophoretic technology which will survive the
termination of the collaboration. The license to Novartis, though non-exclusive,
may make it more difficult for the Company to enter into new collaborations,
which could have a material adverse effect on the Company. Further, other than
in collaboration with Novartis, the Company has agreed that during the term of
the agreement and for a period of up to two years thereafter, the Company will
not develop any product in certain Novartis fields, as defined in the agreement,
without Novartis' consent. There can be no assurance that Novartis will not
terminate its agreement with the Company and independently develop products
using the licensed technology, including products which may compete directly
with those currently marketed or under development by the Company. If Novartis
terminates its agreement with the Company, the Company's business, financial
condition and results of operations could be materially and adversely affected.
 
     In connection with the establishment of the Novartis collaboration, the
Company formed Dermion, Inc. ("Dermion") to perform the Company's research and
development activities and Novartis acquired a 20% equity interest in Dermion.
The Company, Dermion and Novartis recently amended the terms of their
relationships. Under these amendments (the "1997 Amendments"), effective
November 1, 1997, Novartis exchanged its 20% equity interest in Dermion for
238,541 Common Shares and warrants to acquire up to an additional 18,750 Common
Shares at an exercise price of $21.60 per share. Novartis can currently exercise
one-third of the warrants, and its right to exercise the remaining warrants will
vest, as to an additional one-third in each instance, at the time it agrees, if
ever, to provide research and development funding under the parties' agreements
for each of 1999 and 2000. In addition, under the agreement with Novartis, the
Company is restricted in its ability to sell or otherwise dispose of the assets
or control of Dermion through March 1998, and Novartis has a right of first
offer to acquire either the Company's interest in Dermion or Dermion's business
and assets in the event of any proposed change of control of Dermion during the
remainder of the term of the Novartis research and development agreement and for
one year thereafter.
 
     The Company has also agreed that, during the term of the agreement with
Novartis and for a period of five years thereafter, the Company will negotiate
in good faith to license to Novartis rights to any iontophoretic drug delivery
technologies developed or acquired by the Company but which are not covered
under the existing license agreements (the "Second Generation Technology").
Further the Company has agreed to negotiate such additional licenses prior to
entering into any agreement to license or otherwise transfer any rights to such
Second Generation Technology to a third party. Under the 1997 Amendments, the
parties agreed to treat the technology acquired by the Company from Elan
Corporation, plc and its affiliates ("Elan") as Second Generation Technology.
Accordingly, the Company intends to negotiate with Novartis to license such
technology to Novartis prior to initiating efforts to negotiate any rights to
such technology with any third party. See "Business -- Collaborative
Relationships and Licenses."
 
                                       10
<PAGE>   12
 
     Although the Company anticipates it will enter into additional
collaborative arrangements with other parties in the future, there can be no
assurance the Company will be able to negotiate any such additional
collaborative arrangements on terms which are acceptable to the Company, if at
all. In addition, the technology license and rights to future licenses granted
to Novartis may make it more difficult for the Company to find collaborative
partners for its product development programs. To the extent the Company chooses
not, or is not able, to establish such collaborations, it could experience
significantly increased business risk and capital requirements in the
development, clinical testing, manufacturing, marketing and commercialization of
its products. The Company could also encounter significant delays in introducing
products into markets or find that the development, manufacture or sale of
proposed products in such markets is adversely affected by the absence of those
collaborative arrangements.
 
     Under an agreement with a prior collaborative partner, Laboratoires
Fournier S.C.A. ("Laboratoires Fournier"), the Company has agreed, among other
things, not to pursue the development of a fentanyl-based iontophoretic drug
delivery system for chronic pain or sedation, or a hydromorphone-based
iontophoretic drug delivery system for the treatment of acute post-operative
pain, until the second quarter of calendar year 1998. See "Business -- Products
and Products Under Development."
 
     INTENSE COMPETITION AND RAPID TECHNOLOGICAL CHANGE. The drug delivery,
pharmaceutical and biotechnology industries are highly competitive and rapidly
evolving, with significant developments expected to continue at a rapid pace.
The first pharmaceutical product to reach the market in a therapeutic area or
using a certain drug delivery technology generally obtains and maintains a
significant market share relative to later entrants to the market. The Company's
success will depend on its ability to maintain a competitive position and
develop new products and technologies for efficient and cost effective drug
delivery. The Company's products will compete with other formulations of drugs
and with other drug delivery systems, including oral dosage forms, infusions,
injections, inhalants, and transmucosal, transnasal and transdermal products.
There can be no assurance any of the Company's products will have advantages
that will be significant enough to cause medical professionals to prefer or even
use them. New drugs or further development of alternative drug delivery methods
may provide greater therapeutic benefits for a specific drug or indication, or
may offer comparable performance at lower cost, than that offered by the
Company's iontophoretic drug delivery systems, which could have a material
adverse effect on the Company's business, financial condition and results of
operations.
 
     Many competitors, including public and private corporations, academic
institutions, governmental agencies and other public and private research
organizations, are involved in the development of drug delivery systems,
including the development of competing iontophoretic, similar
electrotransport-related or other drug delivery technologies. Many of these
competitors have substantially greater financial, technical, research and other
resources, are more experienced in research and development, manufacturing,
pre-clinical and clinical testing, and obtaining regulatory approvals, and are
larger, more established and have substantially larger marketing and service
organizations than the Company. In addition, these competitors may offer broader
product lines than the Company, have greater name recognition than the Company,
and offer discounts as a competitive tactic. Accordingly, the Company's
competitors may succeed in developing competing technologies, and obtaining FDA
approval or gaining market share for products, more rapidly than the Company.
Many of these competitors currently have drug delivery products that are
approved or in development. There can be no assurance the Company's competitors
will not succeed in developing or marketing products that are more effective or
commercially attractive than the Company's current or future products, or that
would render the Company's products obsolete or noncompetitive. There can also
be no assurance the Company will have the financial resources, technical or
management expertise or manufacturing or support capability to compete in the
future. See "Business -- Competition."
 
     The Company has licensed certain rights to its iontophoretic drug delivery
technologies to other parties, including Alza Corporation ("Alza"), Laboratoires
Fournier and Novartis, that may become or are direct competitors of the Company.
These companies could compete with the Company for contracts with the Company's
collaborative partners and could also develop iontophoretic drug delivery
systems that will compete directly with many of those currently marketed or
being developed by the Company. See "Business -- Collaborative Relationships and
Licenses."

     RELIANCE ON THIRD PARTY DISTRIBUTION; LIMITED SALES AND MARKETING
EXPERTISE. The Company presently markets its drug delivery systems for the
treatment of acute local inflammation primarily to physical therapists through a
nationwide system of dealers. The Company intends to market its local dermal
anesthesia products in the United States hospital market through sales personnel
who work directly for the Company, and anticipates that it will also use a third
party or collaborative partner to market its current and future products. See
"Business -- Sales and Distribution."
 
     The majority of the dealers the Company uses in the distribution of its
drug delivery systems for acute local inflammation are principally involved in
the distribution of electrotherapy equipment and other rehabilitation related
products to physical therapists and related physician specialists. The Company's
product does not represent a primary source of revenue for many of those
dealers. As a result, there can be no assurance those dealers will invest
adequate resources in the sale and promotion of the Company's products, sell
other products developed by the Company or even continue to sell the Company's
products.
 
     In cases where the Company intends to market its products using direct
sales personnel, such as with its drug delivery system for the inducement of
local dermal anesthesia, it will need to hire, train and supervise those
personnel. The Company has limited experience in marketing and sales, and only
recently began to recruit a marketing staff and sales force. The Company will
need to expend additional funds and management resources to assemble, train and
oversee a marketing and sales staff. There can be no assurance the Company can
successfully recruit, hire or retain personnel, nor can there can be any
assurance the Company will be able to maintain its relationships with the
marketing, sales and distribution resources it currently employs. There can also
be no assurance that the cost of establishing and maintaining a sales and
marketing staff will be justifiable in light of product revenues. If the
Company's marketing resources fail to perform in accordance with the Company's
expectations, the Company may be required to obtain or develop alternate
marketing, sales and distribution capabilities or seek other methods of
distributing its products. There can be no assurance the Company would be able
to do so or that the Company's sales and marketing efforts will be successful.
See "Business -- Sales and Distribution."
 
     DEPENDENCE ON PATENTS AND PROPRIETARY TECHNOLOGY. The Company's ability to
commercialize many of the products it has under development will depend, in
part, on its or its licensors' ability, both in the United States and in other
countries, to obtain patents, enforce those patents, preserve trade secrets and
operate without infringing on the proprietary rights of third parties. As of
October 1, 1997, the Company owned or had rights to 60 issued United States
patents, 15 pending United States patents, 245 issued foreign patents and 47
pending foreign patents.
 
     The patent positions of drug delivery, pharmaceutical and biotechnology
companies are highly uncertain and involve complex legal and factual questions.
There can be no assurance the patents currently owned and licensed by the
Company, or any future patents, will prevent other companies from developing
similar or therapeutically equivalent products, or that other companies will not
be issued patents that may prevent the sale of Company products or require
licensing and the payment of significant fees or royalties by the Company.
Furthermore, there can be no assurance any of the Company's products or methods
will be patentable, will not infringe upon the patents of third parties, or that
the Company's patents or future patents will give the Company an exclusive
position in the subject matter claimed by those patents. The Company may be
unable to avoid infringement of third party patents and may have to obtain
licenses, defend infringement actions or challenge the validity of those patents
in court. There can be no assurance a license will be available to the Company,
if at all, on terms and conditions acceptable to the Company, or that the
Company will prevail in any patent litigation. Patent litigation is costly and
time consuming, and there can be no assurance the Company will have or will
devote sufficient resources to pursue such litigation. If the Company does not
obtain a license under such patents, is found liable for infringement or is not
able to have such patents declared invalid, the Company may be liable for
significant monetary damages, may encounter significant delays in bringing
products to market or may be precluded from participating in the manufacture,
use, or sale of products or methods of treatment protected by such patents.
There can be no assurance the pending patent applications licensed to or owned
by the Company will result in issued patents, patent protection will be secured
for any particular technology, any patents that have been or may be issued to
the Company or its
 
                                       12
<PAGE>   14
 
licensors will be valid or enforceable or that the Company's patents will
provide meaningful protection to the Company.
 
     The Company also relies on trade secrets and other unpatented proprietary
information in its product development activities. To the extent the Company
relies on confidential information to maintain its competitive position, there
can be no assurance other parties may not independently develop the same or
similar information. The Company seeks to protect trade secrets and proprietary
knowledge in part through confidentiality agreements with its employees,
consultants, advisors and collaborators. These agreements may not effectively
prevent disclosure of the Company's confidential information and may not provide
the Company with an adequate remedy in the event of unauthorized disclosure of
such information. If the Company's employees, scientific consultants or
collaborators develop inventions or processes independently that may be
applicable to the Company's products under development, disputes may arise about
ownership of proprietary rights to those inventions and processes. Those
inventions and processes will not necessarily become the Company's property, but
may remain the property of those persons or their employers. Protracted and
costly litigation could be necessary to enforce and determine the scope of the
Company's proprietary rights. The Company's failure to obtain or maintain patent
and trade secret protection, for any reason, could have a material adverse
effect on the Company's business, financial position and results of operations.
 
     The Company may engage in collaborations, sponsored research agreements,
and other arrangements with academic researchers and institutions that have
received or may receive funding from United States government agencies. As a
result of these arrangements, the United States government or other parties may
have rights in certain inventions developed during the course of the performance
of such collaborations and agreements as required by law or such agreements.
Several legislative bills affecting patent rights have been introduced in the
United States Congress. These bills address various aspects of patent law,
including publication, patent term, re-examination, subject matter and
enforceability. It is not certain whether any of these bills will be enacted
into law or what form such new laws may take. Accordingly, the effect of such
potential legislative changes on the Company's intellectual property is
uncertain. See "Business -- Patents and Proprietary Rights."
 
     In August 1993, the United States Patent and Trademark Office ("PTO")
issued a patent to Alza covering the iontophoretic delivery of fentanyl. A
similar patent application in Europe has thus far been rejected, although the
Company believes Alza has appealed that rejection. The United States patent was
the subject of a reexamination by the PTO and all of the substantive claims
within the patent were also rejected, but Alza has appealed that rejection to
the United States Board of Patent Appeals and Interferences. There can be no
assurance Alza will not be successful in one or both of its appeals. Therefore,
if the Company develops a drug delivery system for fentanyl and if Alza is
successful in its appeal, the Company would be required to obtain a license from
Alza to market any iontophoretic drug delivery system it develops for fentanyl
in the United States. There can be no assurance such a license would be
available on terms acceptable to the Company, if at all. If the Company cannot
obtain such license, the Company will be required to discontinue its product
development programs using fentanyl. See "Business -- Products and Products
Under Development."
 
     NEED TO MANAGE EXPANDING OPERATIONS. If the Company is successful in
achieving market acceptance of its products, it will be required to expand its
operations, particularly in the areas of research and development, sales and
marketing and manufacturing. As the Company expands its operations in these
areas, those expansions will likely result in new and increased responsibilities
for management personnel and place significant strain on the Company's
management, operating and financial systems and other resources. To accommodate
any such growth and compete effectively, the Company will be required to
implement improved information systems, procedures and controls, and to expand,
train, motivate and manage its work force. The Company's future success will
depend to a significant extent on the ability of its current and future
management personnel to operate effectively both independently and as a group.
There can be no assurance the Company's personnel, systems, procedures and
controls will be adequate to support the Company's future operations.
 
                                       13

     FUTURE CAPITAL NEEDS; UNCERTAINTY OF ADDITIONAL FUNDING. The further
development and commercialization of the Company's products and technology will
require a commitment of substantial funds to conduct research and development
activities, including preclinical and clinical studies, to expand distribution
and hire additional sales and marketing personnel and to expand and develop
manufacturing capabilities. Although the Company believes that the net proceeds
of the Offering, together with existing cash balances and cash generated from
operations, will be sufficient to fund the operations of the Company for
approximately the next two years, the Company may be required or elect to raise
additional capital before that time. The Company's actual capital requirements
will depend on many factors, including but not limited to, the costs and timing
of the Company's research and development activities, the number and type of
clinical tests the Company is required to conduct in seeking approval of its
products from governmental agencies, the success of the Company's development
efforts, the costs and timing of the expansion of the Company's sales and
marketing activities, the extent to which the Company's existing and new
products gain market acceptance, the Company's ability to maintain existing
collaborative relationships and enter into new collaborative relationships,
competing technological and market developments, the progress of the Company's
commercialization efforts and the commercialization efforts of the Company's
distributors, the costs involved in preparing, filing, prosecuting, maintaining,
enforcing and defending patent claims and other intellectual property rights,
developments related to regulatory and third party reimbursement issues, and
other factors.
 
     To satisfy its capital requirements, the Company may seek to raise funds
through public or private financings, collaborative relationships or other
arrangements. Any additional equity financing may be dilutive to shareholders,
and debt financing, if available, may involve significant restrictive covenants.
Collaborative arrangements, if necessary to raise additional funds, may require
the Company to relinquish its rights to certain of its technologies, products or
marketing territories. Failure to raise capital when needed could have a
material adverse effect on the Company's business, financial condition and
results of operations. There can be no assurance that such financing, if
required, will be available on terms satisfactory to the Company, if at all. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources."
 
     UNCERTAINTY OF GOVERNMENT REGULATION. The research, development,
manufacture and marketing of the Company's products are extensively regulated by
the FDA, which requires its approval of drugs and medical devices before they
can be marketed in the United States. Similar approvals are also required from
other regulatory bodies in virtually every developed foreign country before the
Company's products may be marketed in such countries. The regulatory processes
established by these government agencies are lengthy, expensive and uncertain.
In addition, once approval is obtained, that approval may be withdrawn for a
manufacturer's failure to comply with regulatory standards, because of
unforeseen problems related to product safety or as a result of the retroactive
application of changes in the law.
 
     The Company has received approval from the FDA on its New Drug Application
("NDA") for Iontocaine, and the FDA has allowed the Company to market its
electrical dose controllers and electrode products for use with ions of soluble
salts or other drugs under the FDA's 510(k) regulations governing medical
devices. However, the FDA has publicly stated that it intends to require
manufacturers of iontophoretic devices to obtain pre-market approval ("PMA") of
marketed devices currently used with drugs not specifically labeled for
iontophoretic delivery, which would include the Company's dose controller for
use with ions of soluble salts or other drugs, such as Dexamethasone. The FDA's
1994 strategy document states that the enactment of the modified regulatory
procedure was a "high priority" and that the agency intended to publish a
proposed regulation requiring such PMAs in 1996. The agency to date has not
published such a regulation.
 
     If the FDA calls for PMAs, the Company would be required to have a PMA
accepted for filing by the FDA within 90 days after the date of the final
regulation. There can be no assurance that the Company would be able to complete
necessary clinical studies and otherwise prepare and file a PMA within that
period or that any data and information submitted in a PMA would be adequate to
support FDA approval. The Company's failure to submit a PMA and have it accepted
for filing by the FDA within the required timeframe could result in the Company
being required to cease commercial distribution of the Phoresor for use with
ions of soluble salts or other drugs, including Dexamethasone. Upon timely
filing of a PMA, the Company believes (based on
 
                                       14
<PAGE>   16
 
the FDA's announced position as to certain other devices) that the FDA would
permit continued commercial distribution of the Company's dose controller for
use with Dexamethasone during the time necessary to review the PMA. There can be
no assurance, however, that the FDA would do so, nor can any assurance be given
that the FDA would approve a PMA filed by the Company. The FDA also could
condition PMA approval upon approval of an NDA permitting Dexamethasone to be
labeled for use with the Company's dose controller. If the Company were required
to cease commercial distribution of its iontophoretic drug delivery products for
use with Dexamethasone pending approval of a PMA or NDA, the Company's business,
financial conditions and results of operations could be adversely affected. The
Company will be required to obtain further FDA approvals before it may promote
or otherwise market or label any of its present or future drug delivery products
for use with other named drugs. There can be no assurance that such approvals
will be granted, and the process of obtaining them could be extensive,
time-consuming and costly. The time required to obtain FDA approval after filing
an NDA is uncertain and frequently takes several years. Further, the Company has
not yet filed NDAs on any drug other than Iontocaine. In the course of the
practice of medicine, medical practitioners legally can use the Company's
iontophoretic devices for the delivery of Dexamethasone even though the Company
has not filed an NDA for that therapeutic indication and even though the Company
is not permitted to label or promote its device for use with Dexamethasone. The
FDA may require that the Company conduct clinical trials and obtain NDA approval
for the iontophoretic delivery of Dexamethasone using the Company's dose
controllers and electrodes for the treatment of acute local inflammation in
order for the Company to continue to market its products for that therapeutic
indication. There can be no assurance that such clinical trials, if conducted,
would be successful in establishing safety and efficacy or that NDA approval
could be obtained.
 
     There can be no assurance any future products developed by the Company will
prove to be safe and effective or meet all of the applicable regulatory
requirements necessary to be marketed. Data obtained from testing activities can
be susceptible to varying interpretations which could delay, limit or prevent
required regulatory approvals. In addition, the Company may encounter delays or
denials of approval based on a number of factors, including future legislation,
administrative action or changes in FDA policy made during the period of product
development and FDA regulatory review. The Company may encounter similar delays
in foreign countries. Furthermore, approval may entail ongoing requirements for,
among other things, post-marketing studies. Even if a product developer obtains
regulatory approval, a marketed product, its manufacturer and its manufacturing
facilities and pertinent operations are subject to extensive regulation and
periodic inspections. Discovery of previously unknown problems with a product,
manufacturer or facility could result in FDA sanctions, restrictions on a
product or manufacturer, or an order to withdraw and/or recall a specific
product from the market. There can also be no assurance that changes in the
legal or regulatory framework or other subsequent developments will not result
in the limitation, suspension or revocation of regulatory approvals granted to
the Company. Such events, were they to occur, could have a material adverse
effect on the Company's business, financial condition and results of operations.
 
     The Company is also required to comply with FDA regulations for
manufacturing practices, which mandate procedures for extensive control and
documentation of product design, control and validation of the manufacturing
process and overall product quality. Foreign regulatory agencies have similar
manufacturing standards. Ongoing compliance with these standards and with
labeling, adverse event reporting and other applicable regulatory requirements
is monitored through periodic inspections and market surveillance by federal,
state and local government agencies and by comparable agencies in other
countries. Any third parties manufacturing the Company's products or supplying
materials or components for such products may also be subject to the foregoing
requirements. If the Company, its management or its third party manufacturers
fail to comply with applicable regulations regarding these manufacturing
practices, the Company could be subject to a number of sanctions, including
fines, injunctions, civil penalties, delays, suspensions or withdrawals of
market approval, seizures or recalls of products, operating restrictions and, in
some cases, criminal prosecutions. See "Business -- Government Regulation."
 
     Under the FDA's regulations, when a manufacturer changes or modifies a
device for which it has received a 510(k) clearance, it is required to obtain an
additional 510(k) clearance for the modified device if the modification
significantly affects the safety or efficacy of the device, or if the
modification results in a
 
                                       15
<PAGE>   17
 
major change in intended use. In such cases, the manufacturer is expected to
make the initial determination as to whether the modification is of a kind that
would require a new 510(k) clearance. The FDA's regulations provide only limited
guidance in making this determination. The FDA has cleared the Company's
electrical dose controller and electrode kits for marketing under a 510(k)
clearance. Since obtaining its 510(k) clearances, the Company has made
modifications to its products. Based on the checklist developed by the FDA to
assist manufacturers in determining whether they are required to obtain a 510(k)
clearance for a modified device, the Company has determined that a new 510(k)
submission was not required in connection with the commercial introduction of
such products. However, there can be no assurance that the FDA will not require
the Company to obtain additional 510(k) clearances with respect to those
products. If the FDA requires the Company to submit a new 510(k) notice for any
device modification, the Company may be prohibited from marketing the modified
device until the 510(k) notice is cleared by the FDA.
 
     The Company may be subject to certain user fees that the FDA is authorized
to collect under the Food and Drug Modernization Act of 1997, which reauthorized
the user fees established in the Prescription Drug User Fees Act of 1992 for
certain drugs.
 
     Because of the known safety and efficacy profile of Dexamethasone and other
approved drugs for which the Company may seek NDA approval for iontophoretic
delivery, the clinical trials and other studies may not be as lengthy or
extensive as would be required for unapproved new drugs that are subject to full
NDA requirements. This strategy, however, depends upon the Company's ability to
obtain a contractual right to reference the safety and efficacy data for such
drugs contained in approved NDAs held by other entities. The Company has
obtained a right to reference safety and efficacy data for Dexamethasone. There
can be no assurance that the Company will be able to obtain a right of reference
for all unapproved drugs that may be used for iontophoretic delivery. The
Company's failure to obtain a right of reference to safety and efficacy data for
any drug for which the Company would like to obtain approval for iontophoretic
delivery could result in the Company being required to independently satisfy any
requirements regulatory agencies may impose with respect to such references,
which could delay the Company's use of such drug or increase the Company's
costs. See "Business -- Government Regulation."
 
     DEPENDENCE ON SINGLE SOURCES OF SUPPLY. A key material used in many of the
Company's current electrode products is available only from a single supplier.
In addition, the Company obtains Iontocaine from Abbott Laboratories under a
contract expiring in December 1998. The Company also has the right to obtain
Dexamethasone from Luitpold Pharmaceuticals, Inc./American Regent Laboratories,
Inc. under a contract expiring in January 2005. The Company believes that, if
necessary, alternative sources can be developed or alternate materials can be
substituted for each of these single-sourced materials. Although the Company has
not experienced difficulty acquiring these materials on commercially reasonable
terms and in sufficient quantities to maintain required production levels, no
assurance can be given that price increases or interruptions in the supply of
these materials will not occur in the future or that the Company will not have
to seek alternate suppliers or obtain substitute materials, which may require
additional product validations and regulatory submissions. Any significant price
increase, interruption of supply, inability to secure an alternate source or
qualify a substitute material could have a material adverse effect on the
Company's ability to manufacture its products or to obtain or maintain
regulatory approval of its products, any of which could have a material adverse
effect on the Company's business, financial condition and results of operations.
 
     The Company's current dose controllers are manufactured under contract with
a third party electronics manufacturer. The Company has not experienced any
difficulty in obtaining adequate supplies of this product from the manufacturer,
but there can be no assurance that an interruption in supply will not occur in
the future or, if there is an interruption in supply, that the Company would be
able to identify, qualify and validate an alternate source of supply within a
reasonable period of time or that such an interruption would not have a material
adverse effect on the Company's business, financial condition and results of
operations. See "Business -- Manufacturing."
 
     LIMITED MANUFACTURING EXPERIENCE. The Company manufactures its
iontophoretic drug delivery electrodes in quantities sufficient to satisfy its
current level of product sales. To meet anticipated increases in sales, the
Company may need to increase its production significantly beyond its present
manufacturing capacity.
 
                                       16
<PAGE>   18
 
Accordingly, the Company may be required to increase its manufacturing
capacities or to contract with another party to manufacture its products. There
can be no assurance the Company can successfully increase its capacity on a
profitable basis, or contract with another party on terms acceptable to the
Company, if at all.
 
     The Company's manufacturing process is labor intensive and, therefore,
significant increases in production volume will likely require changes in both
product and process design in order to facilitate increased automation in the
Company's production processes. There can be no assurance such changes in
products or processes or efforts to automate all or portions of the Company's
manufacturing process will be successful or that manufacturing or quality
control problems will not arise as the Company increases production volumes of
its existing products or begins production of new products, any of which events
would have a material adverse effect on the Company's business, financial
condition and results of operations.
 
     The Company believes its facilities operate in accordance with the Quality
System Regulations currently prescribed by the FDA and in substantial compliance
with ISO 9001 and CE Mark standards. The Company has Good Manufacturing
Practices ("GMP") audits conducted by a qualified, independent organization on a
regular basis and recently obtained its official ISO 9001, and CE Mark
certification. There can be no assurance the Company will be able to maintain
such compliance, particularly if the scale of the Company's manufacturing
operations increases. See "Use of Proceeds," "Business -- Manufacturing" and
"Business -- Government Regulation."
 
     POTENTIAL HEALTH CARE REFORM. Political, economic and regulatory influences
are subjecting the health care industry in the United States to fundamental
changes. The Company anticipates the United States Congress, state legislatures
and the private sector will continue to review and assess alternative health
care delivery and payment systems. Potential approaches that have been
considered include mandated basic health care benefits, controls on health care
spending through limitations on the growth of private health insurance premiums
and Medicare and Medicaid spending, the creation of large insurance purchasing
groups, price controls and other fundamental changes to the health care delivery
system. The Company believes the legislative debate will continue in the future,
and that market forces will demand reduced costs. The Company cannot predict
what impact the adoption of any future federal or state health care reform
measures, private sector reform or other market forces may have on its business,
either currently or in the future. Even the existence of pending health care
reform could have a material adverse impact on the Company by making it
difficult to raise capital or establish collaborative relationships. See
"Business -- Government Regulation."
 
     UNCERTAINTY OF HEALTH CARE REIMBURSEMENT. The Company's ability to
commercialize its products successfully will depend in part on the extent to
which reimbursement for the costs of those products and related treatments will
be available from government health administration authorities, private health
insurers and other organizations in the United States and in foreign markets
where the Company's products will be sold and used. Third party payors can
affect the pricing or relative attractiveness of the Company's products by
regulating the reimbursement they provide on the Company's or competing products
or therapies. There can be no assurance such reimbursement will continue at
present levels, if at all. Furthermore, significant uncertainty exists as to the
reimbursement status of new health care products. There can be no assurance
third party coverage will be available for the Company's future products at
levels necessary for commercial success. Domestic and foreign government and
third party payors are increasingly attempting to contain health care costs by
limiting both coverage and the level of reimbursement for new therapeutic
products. If adequate coverage and reimbursement levels are not provided by such
government and third party payors for uses of the Company's products, the market
acceptance of those products could be adversely affected. Given the recent
efforts to control and reduce health care costs in the United States and in
foreign markets, there can be no assurance the currently available levels of
reimbursement will continue to be available in the future for the Company's
existing products or products under development.
 
     Effective October 1, 1991, the Health Care Financing Administration adopted
new regulations providing for the treatment of capital related costs for medical
products. Under the regulations, providers are reimbursed for those capital
costs on a per diagnosis basis at fixed rates unrelated to actual costs.
Equipment costs generally are not reimbursed separately, but are included in a
single, fixed rate, per patient reimbursement. These regulations are being
phased in over a 10 year period and, although the full implications of the
 
                                       17
<PAGE>   19
 
regulations cannot yet be known, the Company believes the new regulations may
place more pressure on hospital operating margins, causing them to limit capital
expenditures. The Company is unable to predict what adverse impact on the
Company, if any, additional government regulations, legislation or initiatives
or changes by other payors affecting reimbursement or other matters that may
influence decisions to obtain medical devices may have.
 
     RETENTION AND ATTRACTION OF KEY EMPLOYEES. The Company is highly dependent
on its ability to continue to attract and retain qualified scientific,
managerial and manufacturing personnel. There is intense competition for
qualified personnel in the Company's area of activity, and there can be no
assurance the Company will be able to continue to attract and retain the
qualified personnel necessary for the development of its business. Loss of the
services of or the failure to recruit qualified scientific, managerial or
manufacturing personnel could have a material adverse effect on the Company's
business, financial condition and results of operations. The Company does not
carry key-man insurance with respect to any of its executives or employees. See
"Business -- Employees" and "Management."
 
     RISK OF PRODUCT LIABILITY AND AVAILABILITY OF INSURANCE. The testing,
marketing and sale of drug delivery and related pharmaceutical products for use
in humans involves unavoidable risks. The use of the Company's products in
clinical trials and the sale of its products upon approval may expose the
Company to potential product liability resulting from the use of such products.
In addition, the existence of a product liability claim could have an adverse
effect on the Company's sales of that product, could result in a recall of that
product or require a change in the indications for which it may be used. Product
liability insurance in the Company's industry is expensive and difficult to
obtain.
 
     Although the Company currently has product liability insurance with an
annual limit of $1,000,000 per occurrence and $1,000,000 in the aggregate, there
can be no assurance the existing coverage is adequate. The Company will seek to
maintain and appropriately increase its insurance coverage as its product sales
increase and the clinical development of its new product applications progress.
There can be no assurance, however, that the Company will be able to maintain
its current levels of insurance on acceptable terms, will be able to secure
increased coverage as the commercialization of its products proceeds or that any
particular level of insurance will provide adequate protection against potential
liabilities. The obligation to pay any product liability claim brought against
the Company which is in excess of the Company's insurance coverage could have a
material adverse effect upon the Company's business, financial condition and
results of operations.
 
     ABSENCE OF PRIOR TRADING MARKET; POTENTIAL VOLATILITY OF SHARE PRICE. Prior
to the Offering, there has been no market for the Common Shares, and there can
be no assurance an active trading market will develop or, if one does develop,
that it will be maintained. The public offering price of the Common Shares
offered hereby will be determined by negotiations between the Company and the
representatives of the Underwriters. For a description of the factors to be
considered in determining the public offering price, see "Underwriting." The
market price of the Common Shares, like that of the common shares of many other
drug delivery, pharmaceutical, biotechnology, medical device and other high
technology companies, is likely to be highly volatile. Factors such as
fluctuations or volatility in the Company's operating results, announcements of
technological innovations, results of clinical trials or new commercial products
by the Company or competitors, regulatory developments in the United States or
foreign countries, changes in the current structure of health care financing and
payment systems, developments in or disputes regarding patent or other
proprietary rights, general market conditions, economic and other external
factors may have a significant effect on the market price of the Common Shares.
 
     SHARES ELIGIBLE FOR FUTURE SALE; POSSIBLE ADVERSE EFFECT ON FUTURE MARKET
PRICE. Sales of substantial amounts of Common Shares (including shares issuable
upon exercise of outstanding options and warrants) in the public market after
the Offering could adversely affect the market price of the Common Shares. Such
sales could also make it more difficult for the Company to sell equity
securities or equity-related securities in the future at a time and price that
the Company deems appropriate. Upon completion of the Offering, the Company will
have outstanding an aggregate of 6,360,204 Common Shares. In addition, the
Company has reserved for issuance 679,303 shares issuable upon exercise of
outstanding options and warrants. The 1,700,000 Common Shares offered hereby
will be freely transferable without restriction or further registration
 
                                       18

under the Securities Act of 1933, as amended (the "Securities Act"), except for
shares which may be acquired by "affiliates" of the Company as that term is
defined in Rule 144 under the Securities Act. The remaining Common Shares held
by existing shareholders are "restricted securities" as that term is defined in
Rule 144. Restricted securities may be sold in the public market only if they
are registered or if they qualify for exemption from registration under Rules
144 or 701 or other provisions of the Securities Act. Pursuant to certain
"lock-up" agreements, the Company's directors, officers and certain of its
shareholders who collectively hold an aggregate of 4,560,934 Common Shares,
together with the Company, have agreed, for a period of 180 days following the
date of this Prospectus, not to offer, pledge, sell, contract to sell, grant any
option for the sale of, or otherwise dispose of, directly or indirectly, any
Common Shares without the prior written consent of EVEREN Securities, Inc.
Following the lock-up periods, approximately 1,903,533 Common Shares will be
eligible for sale in the public market without restriction under Rule 144(k) and
an additional 79,808 Common Shares will be eligible for sale subject to certain
volume, manner of sale and other restrictions of Rule 144. All restricted shares
held by existing shareholders of the Company not subject to lock-up agreements
will be eligible for immediate sale in the public market without restriction
under Rule 144(k). In addition, holders of stock options or warrants exercisable
for an aggregate of approximately 220,227 Common Shares have entered into
agreements prohibiting the sales of the underlying Common Shares for 180 days
following the date of this Prospectus. See "Principal Shareholders," "Shares
Eligible for Future Sale" and "Underwriting."
 
     POTENTIAL DILUTION; ABSENCE OF DIVIDENDS. The initial public offering price
will be substantially higher than the tangible book value per Common Share.
Investors purchasing Common Shares in the Offering will therefore incur an
immediate and substantial dilution in tangible book value. In addition,
investors purchasing Common Shares in the Offering will incur additional
dilution to the extent outstanding stock options and warrants are exercised. The
Company has not paid any cash dividends since inception and does not anticipate
paying cash dividends in the foreseeable future. See "Dividend Policy" and
"Dilution." If the initial public offering price is less than $12.00 per share,
the number of Common Shares that Elan will have the right to purchase for the
$10.2 million will be equal to $10.2 million divided by the initial public
offering price. As a result of any issuance to Elan of shares in excess of
833,333, investors in the Offering will own a lower percentage of the total
Common Shares outstanding after the closing of the Offering. See "Transactions
Related to the Offering" and "Certain Transactions."
 
     MANAGEMENT DISCRETION OVER PROCEEDS OF THE OFFERING. The Company's
management will retain broad discretion as to the allocation of a significant
portion of the net proceeds of the Offering. As a result of that discretion, the
Company's management could allocate the proceeds of the Offering to uses which
the shareholders may not deem desirable. In addition, there can be no assurance
the proceeds can or will be invested to yield an appropriate return. See "Use of
Proceeds" and "Management's Discussion and Analysis of Financial Condition and
Results of Operations."
 
     CONTROL BY EXISTING SHAREHOLDERS. Following the Offering, the Company's
directors, executives and principal shareholders will beneficially own
approximately 66.7% of the outstanding Common Shares. Accordingly, if such
persons act in concert, they will have the power to elect the Company's
directors and, subject to certain limitations, effect or preclude fundamental
corporate transactions involving the Company. This concentration of ownership
may have the effect of delaying or preventing a change of control of the
Company. See "Principal Shareholders" and "Description of Capital Shares."
 
     ANTI-TAKEOVER PROVISIONS OF THE COMPANY'S ARTICLES OF INCORPORATION; UTAH
LAW AND CERTAIN OF THE COMPANY'S AGREEMENTS. Certain provisions of the Company's
Articles of Incorporation, as amended, and the provisions of the Utah Revised
Business Corporation Act may have the effect of deterring hostile takeovers or
delaying or preventing changes in control or management of the Company,
including transactions in which shareholders might otherwise receive a premium
for their shares over then-current market prices. The Company's Articles of
Incorporation provide, among other things, for a classified Board of Directors,
and provide that members of the Board of Directors may be removed only for cause
upon the affirmative vote of the holders of at least two-thirds of the Common
Shares. The Company's Board of Directors is also authorized to issue Preferred
Shares and, in connection with any such issuance, determine the price, rights,
preferences and privileges of those shares without further vote or action by the
Company's shareholders. Any such
 
                                       19
<PAGE>   21
 
Preferred Shares may have other rights, including economic rights, which are
senior to the Common Shares and, as a result, the issuance of such Preferred
Shares could have a material adverse effect on the market value of the Common
Shares. See "Description of Capital Shares."
 
     Certain of the provisions of a cross-license agreement between the Company
and Alza may have the effect of deferring, delaying or preventing a change in
control of the Company, a merger involving the Company or the assignment or
transfer of certain technologies of the Company. Under the agreement, the
Company and Alza, among other things, exchanged non-exclusive, royalty free
rights to certain patented technologies which each party believed to be of
significant strategic importance to the potential technological success of many
iontophoretic drug delivery applications. Both parties are prohibited from
assigning their rights under the agreement to certain named companies or any
other entity that derives more than 50 percent of its income from the
development, licensing and/or sale of drug delivery systems to other
pharmaceutical companies without first receiving the consent of the other party.
Restrictions imposed on the Company's ability to assign its rights under this
agreement may limit the Company's ability to capitalize on the commercial and
other economic potential of these technologies through a technology license,
asset sale, merger, combination or similar transaction, and could have an
adverse effect on the market value of the Common Shares. See
"Business -- Collaborative Relationships and Licenses."
 
     ENVIRONMENTAL MATTERS. The Company's research and development activities
involve the controlled use of hazardous materials, chemicals and various
radioactive compounds. These materials, and their use, disposal and handling,
are extensively regulated by federal, state and local government authorities.
Although the Company believes its safety procedures for handling and disposing
of such materials comply in all material respects with the standards prescribed
by state and federal regulations, the risk of accidental environmental
contamination or personal injury from these materials cannot be completely
eliminated. In the event of such an accident, the Company could be held liable
for any damages and any such liability could exceed the resources of the
Company. There can be no assurance the Company will not be required to incur
significant costs to comply with such environmental and health and safety laws
and regulations in the future, particularly if the Company develops additional
manufacturing or research facilities and capacity. See "Business -- Government
Regulation."
 
     FORWARD-LOOKING STATEMENTS. Certain statements under the headings
"Prospectus Summary," "Risk Factors," "Use of Proceeds," "Management's
Discussion and Analysis of Financial Condition and Results of Operations,"
"Business," and elsewhere in this Prospectus constitute "forward-looking
statements" within the meaning of the rules and regulations promulgated by the
Securities and Exchange Commission. Such forward-looking statements may be
identified by the use of terminology such as "may," "will," "expect,"
"anticipate," "intend," "designed," "estimate," "should," or "continue" or the
negatives thereof or other variations thereon or comparable terminology. Such
forward-looking statements involve known and unknown risks, uncertainties and
other factors which may cause the actual results, performance or achievements of
the Company, or industry results, to be materially different from any future
results, performance or achievements expressed or implied by such
forward-looking statements. These risks, uncertainties and other factors
include, among other things, the following: the Company's sporadic history of
profitability and the continuing uncertainty of its profitability; the Company's
ability to develop and introduce new products; the uncertainty of market
acceptance of the Company's new and existing products and their market
penetration to date; the uncertainties related to the Company's product
development programs; the Company's reliance on collaborative partners and
licenses; the Company's limited sales, marketing and distribution experience and
current dependence on distributors; the risks associated with obtaining
governmental approval of the Company's products; the highly competitive industry
in which the Company operates and the rapid pace of technological change within
that industry; the uncertainty of patented and proprietary technology protection
and the Company's reliance on such patented and proprietary technology
(including reliance on technology licensed from third parties); changes in or
failure to comply with governmental regulation, the uncertainty of third party
reimbursement for the Company's products; the Company's dependence on key
employees; general economic and business conditions and other factors referenced
in this Prospectus.

                      TRANSACTIONS RELATED TO THE OFFERING
 
     In March 1997, the Company entered into a series of agreements with Elan
pursuant to which the Company acquired certain in-process research and
development programs, including exclusive world-wide rights to certain
iontophoretic patents, know-how and clinical data (the "Elan Agreements"). The
Company acquired the Elan technology by issuing Elan two promissory notes, a
$10.0 million note and a $5.0 million note (collectively, the "Elan Notes"),
together with a warrant to purchase 104,166 Common Shares at an exercise price
of $21.60 per share and agreed to pay Elan royalties on any net revenues derived
by the Company from its products.
 
     Concurrently with the closing of the Offering, Elan will purchase directly
from the Company, in private placement transactions (i) 833,333 Common Shares
(subject to adjustment under certain circumstances) for approximately $10.2
million (the amount outstanding under the $10.0 million note) and (ii)
approximately $5.1 million of Common Shares at a price per share equal to the
initial public offering price hereunder (425,000 shares assuming an initial
public offering price of $12.00 per share) (collectively, the "Elan Shares").
Simultaneously with such purchases, the Company will repay the Elan Notes,
including interest thereon. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations," "Business -- Collaborative
Relationships and Licenses," "Certain Transactions," "Description of Capital
Shares -- Warrants" and "Underwriting."
 
     If the initial public offering price of the Common Shares is less than
$12.00 per share, the number of Common Shares that Elan will have the right to
purchase for the approximately $10.2 million (the amount outstanding under the
$10.0 million note) will be equal to that amount divided by the initial offering
price. If, as a result of Elan's purchase of the Elan Shares, Elan's aggregate
interest in the Common Shares exceeds 19.9% of the outstanding Common Shares,
Elan may elect to receive non-voting preferred shares to the extent of such
excess. Any such preferred shares would rank pari passu with the Common Shares,
and would be non-voting and convertible into Common Shares on a one-for-one
basis initially. See "Certain Transactions."
 
     Effective November 1, 1997, the Company, Novartis and Dermion amended the
terms of their contractual relationships. Among other things, Novartis exchanged
its 20% interest in Dermion for 238,541 Common Shares and warrants to acquire an
additional 18,750 Common Shares at an exercise price of $21.60 per share. See
"Business -- Collaborative Relationships and Licenses" and "Description of
Capital Shares -- Warrants."

<PAGE>   23
 
                                USE OF PROCEEDS
 
     The net proceeds of the Offering are estimated to be approximately $18.1
million ($20.9 million if the Underwriters' exercise the over-allotment option
in full) at an assumed initial public offering price of $12.00 per Common Share.
The Company intends to use approximately $11.8 million of the net proceeds from
the Offering to conduct research and development activities. The balance of the
net proceeds (approximately $6.3 million) will be used to expand the Company's
sales and marketing capabilities and to consolidate and equip its facilities, as
well as for working capital or other general corporate purposes. The Company may
also use a portion of the net proceeds from the Offering for the in-licensing or
acquisition of technologies, businesses or products that are complementary to
those of the Company, although no specific acquisitions are being negotiated as
of the date hereof, and no portion of the net proceeds has been allocated for
any such acquisition. Pending such uses, the Company intends to invest the
proceeds of the Offering in short term, investment grade, interest-bearing
securities. See "Transactions Related to the Offering" and "Certain
Transactions."
 
     Elan has agreed to purchase in private placement transactions concurrently
with the closing of the Offering the Elan Shares for approximately $15.3
million. Simultaneously with such purchases, the Company will repay the Elan
Notes, including interest thereon. See "Transactions Related to the Offering"
and "Certain Transactions."
 
     The actual amount expended and the timing of the use of the net proceeds of
the Offering for each purpose set forth in the preceding paragraph may vary
significantly depending upon a number of factors, including the costs and timing
of the Company's research and development activities, the number and type of
clinical tests the Company is required to conduct in seeking approval of its
products from governmental agencies, the success of the Company's developmental
efforts, the costs and timing of the expansion of the Company's sales and
marketing activities, the extent to which the Company's existing and new
products gain market acceptance, the Company's ability to maintain existing
collaborative relationships and enter into new collaborative relationships,
competing technological, market and patent developments, the progress of the
Company's commercialization efforts and the commercialization efforts of the
Company's distributors and co-marketers, the costs involved in preparing,
filing, prosecuting, maintaining and enforcing patent claims and other
intellectual property rights, developments related to regulatory and third party
reimbursement issues, and other factors. The Company's management will retain
broad discretion as to the allocation of a significant portion of the net
proceeds of the Offering. See "Risk Factors -- Management Discretion Over
Proceeds of the Offering."

simultaneous repayment of the Elan Notes, including interest thereon,
concurrently with the closing of the Offering; (iii) the mandatory conversion of
the outstanding Series C Preferred Shares into 28,800 Common Shares concurrently
with the closing of the Offering; and (iv) the exchange of Novartis' 20% equity
interest in Dermion for 238,541 Common Shares, which was effected November 1,
1997. The number of the Elan Shares is dependent upon the initial public
offering price. See "Transactions Related to the Offering" and "Certain
Transactions."

                                    DILUTION
 
     The pro forma net tangible book value of the Company as of September 30,
1997 (giving effect to the 1-for-4.8 reverse split), was $7,483,000, or $1.61
per share. Pro forma net tangible book value per share is equal to total
tangible assets of the Company, less total pro forma liabilities, divided by the
pro forma number of Common Shares outstanding, giving effect to (i) the sale of
the Elan Shares to Elan and the simultaneous repayment of the Elan Notes,
including interest thereon, concurrently with the closing of the Offering; (ii)
the mandatory conversion of the outstanding Series C Preferred Shares into
28,800 Common Shares concurrently with the closing of the Offering; and (iii)
the exchange of Novartis' 20% equity interest in Dermion for 238,541 Common
Shares, which was effected November 1, 1997. Without taking into account any
other changes in pro forma net tangible book value after September 30, 1997
other than to give effect to the issuance and sale of the 1,700,000 Common
Shares offered hereby at an assumed initial public offering price of $12.00 per
share and the receipt of the net proceeds therefrom, the pro forma net tangible
book value of the Company as of September 30, 1997 would have been approximately
$25,684,000, or $4.04 per share. This represents an immediate increase in pro
forma net tangible book value of $2.43 per share to existing shareholders and an
immediate dilution in pro forma net tangible book value of $7.96 per share to
investors in the Common Shares offered hereby. The number of the Elan Shares is
dependent upon the initial public offering price, See "Transactions Related to
the Offering" and "Certain Transactions." The following table illustrates the

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     The following should be read in conjunction with "Selected Consolidated
Financial Data" and the Company's Consolidated Financial Statements and Notes
thereto appearing elsewhere in this Prospectus. This Management's Discussion and
Analysis of Financial Condition and Results of Operations and other parts of
this Prospectus contain forward-looking statements that involve risks and
uncertainties. The Company's actual results may differ significantly from the
results discussed in the forward-looking statements. Factors that might cause
such a difference include, but are not limited to, those discussed in "Risk
Factors."
 
OVERVIEW
 
     The Company develops, manufactures and commercializes controllable drug
delivery systems using iontophoretic technology. The majority of the Company's
revenues has been generated through the sale of its iontophoretic drug delivery
products in the physical therapy market for use in the delivery of Dexamethasone
and contract research revenues from the Company's collaboration with Novartis.
The Company recently introduced its local dermal anesthesia products into the
market place and, to date, has not realized significant revenue from the sales
of such products. Since its inception, the Company has generally incurred
operating losses and it expects to incur additional operating losses over the
next several years as a result of anticipated costs associated with a
significant increase in internally funded research, development and clinical
trial activities relating to new applications for its iontophoretic drug
delivery technologies, development of a dedicated sales force and the
consolidation and equipping of its facilities. As of September 30, 1997, the
Company's accumulated deficit was approximately $21.6 million. The Company's
ability to achieve and sustain profitability will depend on its ability to
achieve market acceptance and successfully expand sales of its existing
products, as well as successfully complete the development of, receive
regulatory approvals for, and successfully manufacture and market, its products
under development, as to which there can be no assurance.
 
RESULTS OF OPERATIONS
 
  THREE MONTHS ENDED SEPTEMBER 30, 1996 AND 1997
 
     Revenues. Product sales increased 10% from $1.8 million in the three months
ended September 30, 1996 to $2.0 million in the three months ended September 30,
1997. The increase can be attributed to higher sales of the Company's
iontophoretic drug delivery products for the treatment of local inflammatory
conditions resulting from overall market growth in this segment.
 
     Contract research revenues, royalties and license fees decreased 23% from
$649,000 in the three months ended September 30, 1996 to $503,000 in the three
months ended September 30, 1997. This decrease can be attributed to the
Company's receipt of a milestone payment pursuant to its research and
development agreement with Novartis during the three months ended September 30,
1996.
 
     Costs of Products Sold. Costs of products sold increased 9% from $821,000
in the three months ended September 30, 1996 to $893,000 in the three months
ended September 30, 1997, reflecting increased material and labor costs
associated with higher unit sales volume.
 
     Research and Development Expense. Research and development expenditures
decreased 4% from $391,000 in the three months ended September 30, 1996 to
$375,000 in the three months ended September 30, 1997. This decrease reflects
differences in the timing of certain expenditures on the Company's internally
financed product development projects.
 
     Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased 38%, from $769,000 in the three months ended
September 30, 1996 to $1.1 million in the three months ended September 30, 1997.
The increase to the current period can be attributed primarily to the
recruiting, personnel and other sales and marketing costs associated with the
Company's continued investment in the market introduction of Numby Stuff. In
addition, the Company realized increased costs associated with routine
maintenance and prosecution of the patent portfolio acquired from Elan.
 
                                       26
<PAGE>   28
 
     Other Costs and Expenses. Interest expense increased from $1,000 in the
three months ended September 30, 1996 to $287,000 in the three months ended
September 30, 1997. This increase can be attributed to the recognition of
non-cash interest expense on $15.0 million in notes issued to Elan in connection
with the Elan Agreements. Interest income and other miscellaneous income was
$58,000 in the three months ended September 30, 1996, compared to $91,000 in the
three months ended September 30, 1997, reflecting interest earnings on higher
average invested cash balances during the current period.
 
     The Company has substantial net operating loss carryforwards which, under
the current "change of ownership" rules of the Internal Revenue Code, may be
subject to substantial annual limitation. Income taxes for the three months
ended September 30, 1996 reflect the Company's effective income tax rate for
fiscal 1997. No income tax expense was recognized for the three months ended
September 30, 1997, which reflects management's estimate of its fiscal 1998 tax
position.
 
     Income (loss) from Continuing Operations. Income from continuing operations
of $474,000 in the three months ended September 30, 1996 compares to a loss from
continuing operations of $36,000 in the three months ended September 30, 1997.
The decrease in fiscal 1997 can be attributed to the receipt of the milestone
payment from Novartis in the prior year, non-cash interest charges on the Elan
indebtedness and the Company's investment in the sales and marketing of Numby
Stuff.
 
  FISCAL YEARS ENDED JUNE 30, 1996 AND 1997
 
     Revenues. Product sales increased 10% from $6.8 million in fiscal 1996 to
$7.5 million in fiscal 1997. This increase can be attributed to increased sales
of the Company's iontophoretic drug delivery products for the treatment of local
inflammatory conditions resulting from the first full year of sales of the
Company's newly introduced electrode kits for this market segment.
 
     Contract research revenues, royalties and license fees decreased 25% from
$2.4 million in fiscal 1996 to $1.8 million in fiscal 1997. During fiscal 1996,
the Company entered into a research and development agreement with Novartis to
develop proprietary iontophoretic drug delivery systems for Novartis drugs.
Pursuant to the agreement, the Company received contract research revenues and
other payments of $1.4 million and $1.8 million, respectively, in fiscal 1996
and 1997. In addition, in fiscal 1996, the Company received a one-time license
fee of $1.0 million. Contract research revenues received during fiscal 1997 and
1996 pursuant to the Novartis agreement covered a substantial portion of the
Company's research and development expenses.
 
     Costs of Products Sold. Costs of products sold increased 6% from $3.1
million in fiscal 1996 to $3.3 million in fiscal 1997, reflecting increased
costs attributable to higher material and labor costs resulting from higher unit
sales volume. Costs of products sold decreased slightly as a percent of product
sales due to productivity gains which were offset, in part, by increased costs
associated with new product introductions.
 
     Research and Development Expense. Research and development expenditures
increased 36%, from $1.1 million in fiscal 1996 to $1.5 million in fiscal 1997.
The increase reflects increased costs of personnel and other expenditures
associated with the development programs conducted under the Novartis agreement,
as well as research and development expenditures on the Company's internally
financed product development projects.
 
     Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased 6%, from $3.3 million in fiscal 1996 to $3.5
million in fiscal 1997. The increase in fiscal 1997 can be attributed to the
recruiting, personnel and other sales and marketing costs associated with the
Company's market introduction of Numby Stuff. The increase was offset, in part,
by decreases in general and administrative expenses.
 
     Non-Recurring Charges. In March 1997, the Company entered into the Elan
Agreements, pursuant to which the Company acquired certain rights to Elan's
in-process research and development relating to iontophoretic drug delivery,
including issued and pending United States and foreign patents, know-how and
clinical data. As a result of this transaction, the Company recorded a
non-recurring charge of approximately $15.1 million.
 
                                       27
<PAGE>   29
 
     During fiscal 1996, the Company recorded a non-recurring charge of $430,000
for costs incurred in connection with the settlement of a trade-dress
infringement suit brought by a competitor of the Company relating to a newly
developed series of the Company's electrode kits for the treatment of acute
local inflammation (the "Litigation").
 
     Other Costs and Expenses. Interest expense increased from $9,000 in fiscal
1996 to $242,000 in fiscal 1997. This increase can be attributed to the
recognition of non-cash interest expense on $15.0 million in notes issued to
Elan in connection with the Elan Agreements. Interest income and other
miscellaneous income was $167,000 in fiscal 1996, compared to $291,000 in fiscal
1997, reflecting interest earnings on higher average cash balances during fiscal
1997.
 
     The Company has substantial net operating loss carryforwards. Income taxes
in both periods reflect estimated alternative minimum tax liabilities, offset by
the recognition of future tax benefits resulting from the allocation of income
tax expense, at statutory rates, to the pre-tax income of the Company's
discontinued operations.
 
     Income (loss) from Continuing Operations. Income from continuing operations
of $1.5 million in fiscal 1996 compares to a loss from continuing operations of
$14.1 million in fiscal 1997. Excluding the non-recurring charges in both fiscal
years, income from continuing operations decreased from $2.0 million in fiscal
1996 to $1.0 million in fiscal 1997. The decrease in fiscal 1997 can be
attributed primarily to the one time $1.0 million license fee the Company
received from Novartis in fiscal 1996.
 
  FISCAL YEARS ENDED JUNE 30, 1995 AND 1996
 
     Revenues. Product sales decreased 3% from $7.0 million in fiscal 1995 to
$6.8 million in fiscal 1996. Sales increases during fiscal 1996 were offset by
the full year effect of the loss of sales resulting from the acquisition, during
fiscal 1995, of several of the Company's key product distributors by a major
competitor in the physical therapy market. Sales in fiscal 1996 were also
negatively impacted by the Litigation, which delayed the launch of the newly
developed series of electrode kits for the treatment of acute local
inflammation. During fiscal 1996, the Company realized $1.4 million in revenues
from contract research and development services and a one-time $1.0 million
license fee in connection with its research and development agreement with
Novartis, offsetting the decrease in product sales in fiscal 1996.
 
     Cost of Products Sold. Costs of products sold decreased 9% from $3.4
million in fiscal 1995 to $3.1 million in fiscal 1996. This improvement was
attributed to increased manufacturing efficiencies and lower materials costs
resulting from the use of new materials and sources of supply and reductions in
manufacturing overhead.
 
     Research and Development Expense. Research and development expense
decreased 27% from $1.5 million in fiscal 1995 to $1.1 million in fiscal 1996.
Research and development expense during fiscal 1996 consisted primarily of
expenditures relating to the Company's research programs with Novartis, which,
in the aggregate, were lower than the research and development expenditures in
fiscal 1995. The Company's research and development expenditures in fiscal 1995
included costs relating to the Company's NDA filing for the approval of
Iontocaine, as well as expenditures relating to the Company's collaborative
development projects with Laboratoires Fournier.
 
     Non-Recurring Charges. The Company recorded a non-recurring charge of
$430,000 during fiscal 1996 for costs incurred in connection with the
Litigation.
 
     Other Costs and Expenses. Interest expense decreased from $32,000 in fiscal
1995 to $9,000 in fiscal 1996 due to the lower average principal balance due
under the Company's term loan. Interest income and other miscellaneous income
was $120,000 in fiscal 1995, compared to $167,000 in fiscal 1996, primarily due
to interest earnings on higher average cash balances from operating cash flows,
and the Company's sale to Novartis of a 20% interest in Dermion in fiscal 1996.
 
     The Company has substantial net operating loss carryforwards. The credit
provision for income taxes in fiscal 1996 reflects the recognition of future tax
benefits resulting from the allocation of income tax expense, at
 
                                       28
<PAGE>   30
 
statutory rates, to the pre-tax income of the Company's discontinued operations,
offset, in part, by estimated alternative minimum tax liabilities. The credit
provision for income taxes in fiscal 1995 reflects the recognition of future tax
benefits resulting from the allocation of income tax expense, at statutory
rates, to the pre-tax income of the Company's discontinued operations.
 
     Income (loss) from Continuing Operations. The loss from continuing
operations of $949,000 in fiscal 1995 compares to income from continuing
operations of $1.5 million in fiscal 1996. Excluding the non-recurring charge in
fiscal 1996, the difference is attributable primarily to the Company's receipt,
in fiscal 1996, of contract research and development revenues and a $1.0 million
one-time license fee in connection with the Company's research and development
agreement with Novartis.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     Prior to fiscal 1996, the Company funded its operating losses primarily
through private equity financing, convertible debt arrangements, capital lease
financing, and collateralized bank loans. Beginning in fiscal 1996, the
Company's operating and research activities have been internally funded,
primarily as a result of the research and development revenues and license fees
the Company has received from Novartis.
 
     As of September 30, 1997, the Company had cash and cash equivalents
totaling approximately $5.9 million. Cash in excess of immediate requirements is
invested in a manner which is intended to maximize liquidity and return while
minimizing investment risk, and, whenever possible, the Company seeks to
minimize the potential effects of concentration of credit risk.
 
     In the three month period ended September 30, 1996, the Company generated
$829,000 of cash from operating activities compared to a use of cash of
approximately $194,000 in the three month period ended September 30, 1997. This
decrease in cash flow is due to the Company's net loss for the current period,
as discussed above, and to changes in working capital during the three month
period ended September 30, 1997. The Company generated approximately $1.0
million of cash from operating activities during fiscal 1997, compared to $2.2
million in fiscal 1996. The decrease can be attributed primarily to the one-time
license fee received from Novartis in fiscal 1996 and an increased net
investment in working capital in fiscal 1997. In fiscal 1996, the Company
generated cash of $2.2 million from operating activities, compared to a use of
cash of $298,000 in fiscal 1995. The transition to generating cash in fiscal
1996 can be attributed to the research and development funding and the one-time
license fee the Company received from Novartis in fiscal 1996. During fiscal
1995, the Company's investment in finished goods inventory increased in
preparation for the launch of a new electrode kit for local inflammation and
accrued liabilities increased due to the reserve established for the estimated
costs of the Company's planned facilities consolidation.
 
     Historically, the Company's operations have not been capital intensive and,
therefore, its investment in property, plant and equipment during the periods
presented has not been significant. The Company anticipates however, that its
investment in facilities and equipment will increase in the future, due to the
Company's desire to consolidate its manufacturing, administrative and research
and development facilities and the need to increase the automation of its
electrode manufacturing processes to meet higher expected sales volumes. The
Company's expenditures for equipment and furniture were $156,000, $316,000 and
$231,000 in each of the fiscal years ended June 30, 1995, 1996 and 1997,
respectively.
 
     During fiscal 1997, the Company generated $255,000 in cash from the private
placement of its Common Shares. During fiscal 1996, the Company generated $1.0
million ($892,000, net of related expenses) in cash from the sale of a 20%
equity interest in Dermion to Novartis. See "Transactions Related to the
Offering."
 
     The Company expects to continue to incur substantial costs associated with
the expansion of its research and development activities, including clinical
trials, development of a dedicated sales force and consolidating and equipping
its facilities. The Company anticipates that the net proceeds of the Offering,
together with existing cash balances and cash generated from operations
(including funding from Novartis) will be sufficient to fund the operations of
the Company for approximately the next two years. However, the Company may be
required or elect to raise additional capital before that time. The Company's
actual capital requirements will
 
                                       29
<PAGE>   31
 
depend on many factors, some of which are outside the Company's control. See
"Risk Factors -- Future Capital Needs; Uncertainty of Additional Funding" and
"Use of Proceeds."
 
     Concurrently with the closing of the Offering, Elan has agreed to purchase
the Elan Shares directly from the Company, in private placement transactions,
for approximately $15.3 million. Simultaneously with Elan's purchase of such
shares, the Company will repay the Elan Notes, including interest thereon. See
"Transactions Related to the Offering," "Certain Transactions" and Note 7 of the
Notes to Consolidated Financial Statements.
 
DISCONTINUED OPERATIONS
 
     Prior to January 1997, the Company provided state-of-the-art prosthetics
products to amputees throughout the United States, Canada and Western Europe
through its Motion Control division. Motion Control's principal products were
the Utah Artificial Arm and the ProControl II, advanced myolectric prostheses
for above and below the elbow amputees.
 
     In December 1996, the Company sold the assets of the Motion Control
division for $1.0 million and granted the purchaser an exclusive, worldwide
license and sublicense to the patents, trademarks, know-how and other
intellectual property of the Company relating to the Motion Control products.
Under the terms of that sublicense agreement, the Company will receive license
fees and royalties on future sales of the Motion Control products. There was no
significant gain or loss recognized on the sale. The results of operations of
the Motion Control division, exclusive of any corporate allocations, are
reported as discontinued operations in the consolidated financial statements for
all periods presented. See Note 4 of the Notes to the Consolidated Financial
Statements.

INTRODUCTION
 
     The Company develops, manufactures and commercializes controllable drug
delivery systems using iontophoretic technology. Iontophoresis is a non-invasive
method of enhancing and controlling the transport of water-soluble ionic drugs
into and through the skin using a low level electrical current. The Company's
proprietary iontophoretic drug delivery systems allow rapid onset and cessation
of therapeutic action, as well as programmable dose control. The systems enable
caregivers and patients to control the onset of drug effectiveness and maintain,
reduce or cease drug administration once a desired therapeutic effect is
observed. The programming feature also enables caregivers to customize dosing
patterns to meet each patient's specific needs. The Company is developing
systems designed to enable patient monitoring and control. The flexibility of
the Company's proprietary systems provides therapeutic control not possible with
many alternative drug delivery methods, including oral tablets and capsules,
injections, inhalants and passive transdermal patches. The Company's systems may
also increase bioavailability, safety and patient comfort.
 
     The Company markets two products, an iontophoretic system used to deliver
Dexamethasone and an iontophoretic system used to deliver Iontocaine. Since it
was introduced in 1979, the Company's system for the delivery of Dexamethasone
has been used primarily by physical therapists and athletic trainers in over 10
million patient applications for the treatment of acute local inflammatory
conditions such as tendonitis, tennis elbow and carpal tunnel syndrome. More
than 8 million of these applications have occurred since 1990, when the Company
introduced its present family of gel electrodes for use with its microprocessor
controlled dose controller. The Company's system to deliver Iontocaine provides
needle-free, long-lasting local dermal anesthesia up to six times more rapidly
and up to three times deeper than can be achieved using topical anesthetic
creams. The Company is initially marketing its Iontocaine product under the
brand name Numby Stuff in pediatric hospitals in the United States. The Company
is also developing a number of iontophoretic drug delivery systems for other
indications, including conscious sedation, tocolysis, post operative and chronic
pain control, and osteoporosis.
 
BACKGROUND ON DRUG DELIVERY SYSTEMS
 
     A wide variety of drug delivery methods is currently available in the
market, although not all drugs can be delivered by all routes of administration.
For certain applications, there are clinical benefits in providing rapid onset
of therapeutic action and the minimum drug dosage necessary to achieve the
desired effect. In all applications, drug delivery should be convenient, cost
effective and as non-invasive as possible.
 
     Conventional Oral Methods. Conventional oral drug dosage forms, such as
pills and capsules, are the most common types of drug delivery. These methods
offer ease of administration and low cost-per-use, but their application is
often limited by inconvenient dosage intervals and less than optimal
bioavailability (due to degradation of the drug in the gastro intestinal tract
("GI tract") and the liver) and efficacy. In addition, conventional oral dosage
forms often produce higher initial drug levels than are required to achieve the
desired therapeutic effects, thereby increasing the risk of side effects and
lower than therapeutically optimal levels of the drug as it is metabolized and
cleared from the body. More frequent administration of lower doses can sometimes
mitigate this problem, but can also increase cost, inconvenience and patient
noncompliance.
 
     Injection Methods. Injectable drug dosage forms generally provide rapid
onset of action and offer many of the same advantages as conventional oral drug
dosage methods. Like conventional oral dosage forms, however, they often produce
higher initial drug levels than are required to achieve the desired therapeutic
effect, thereby increasing risk of side effects. Injectable drug delivery
methods require caregiver administration and have the added disadvantage of
using needles as a delivery path into the body, raising the possibility of
needle stick injuries, as well as risk of infection to the caregiver and the
patient. The use of needles also increases patient anxiety due to the pain of
injection.
 
     Controlled Release Methods. Controlled release drug delivery systems
attempt to overcome many of the limitations inherent in conventional drug
delivery methods by maintaining a more consistent and appropriate drug level in
the bloodstream. Sustained release oral dosage forms are designed to release the
active
 
                                       31
<PAGE>   33
 
ingredients of the drug into the body at either a predetermined point in time or
at a predetermined rate over an extended period of time, but they generally do
not provide rapid onset of action and may not achieve optimal bioavailability.
Passive transdermal patches allow absorption of drugs through the skin and
generally provide a convenient method of administering drugs at a steady rate
over an extended period of time, but onset of action may take hours after
application and absorption of the drug may continue for hours after the patch is
removed, which can increase side effects. Additionally, because human skin is an
effective barrier, most drug formulations will not passively permeate the skin
in therapeutic quantities. Continuous infusion pumps introduce drugs directly
into the body, thereby providing rapid onset of action, and may offer variable
controlled dosing. Infusion therapy requires insertion of a needle, however,
and, therefore, can be painful and threatening to the patient. The use of
infusion pumps also increases the risk of infection and generally requires
medical professionals for safe administration, which may significantly increase
costs.
 
     Pulmonary and Nasal Methods. Both pulmonary (inhalation) delivery and nasal
sprays are designed to provide rapid onset of action or to deliver drugs that
are not orally bioavailable. Pulmonary delivery has the disadvantage of variable
drug amounts reaching the alveoli of the lungs, therefore making it difficult to
control the bioavailability of the dose. Nasal sprays can cause irritation in
some patients and can be difficult to administer in variable intranasal
conditions. In addition, the dose of the product cannot be controlled by the
patient over a period of time, and patients and caregivers may have difficulty
maintaining the desired therapeutic effect.
 
     Other. Many existing and emerging pharmaceutical compounds, such as
biotechnology-derived oligonucleotides, peptides and other macromolecular drugs,
cannot be effectively administered by traditional non-invasive methods and are,
therefore, administered only by injection or infusion. Oral delivery of such
molecules is generally inefficient due to the rapid breakdown of the molecules
during digestion and the natural impermeability of the GI tract to larger
molecules. The skin is even less permeable to macromolecules than the GI tract,
which the Company believes is the primary reason passive transdermal delivery of
those molecules using patch technology has not been successful to date.
 
IONTOPHORETIC DRUG DELIVERY AND ITS ADVANTAGES
 
     Iontophoretic drug delivery systems are designed to overcome many of the
limitations associated with many other drug delivery methods. Iontophoresis is
an active method of transdermal drug delivery in which water-soluble, ionized
(electrically charged) drugs are transported through the skin for local or
systemic therapeutic applications by applying a low level, external electrical
current. The amount of drug delivered through the skin is proportional to the
total electrical charge applied (which is a function of time and current).
Therefore, it is possible to program the system's electrical current levels to
control more precisely the desired drug dose, delivery rate and the pattern of
delivery.
 
     Iontophoretic drug delivery systems are generally comprised of a power
supply which is used to control drug dose (the "dose controller") and a pair of
electrodes, one containing the drug and one serving as a grounding electrode to
complete the electrical circuit through the skin. The drug electrode consists of
a matrix which contains the drug solution, a conductive element which
distributes the electric current through the drug matrix, an electrical
connector that links the electrode to the dose controller, and an adhesive layer
that attaches the electrode to the body. The grounding electrode consists of
similar components, but without the drug solution. The drug delivery electrode
is applied to the patient's skin at a local treatment site (such as for joint or
tendon soreness or to induce local dermal anesthesia), or at any suitable site
on the body for systemic drug delivery. The grounding electrode is applied to
the skin a short distance away from the drug electrode. As is shown in the
following illustration, when an electric current with the same positive or
negative electric charge as the drug is applied to the drug electrode, the drug
is repelled from the electrode and into the skin in the same way as like poles
of two magnets repel each other. Although the Company's currently marketed
products consist of discrete components, the Company has begun the development
of more advanced systems which integrate all components in a single miniaturized
patch.
 
                                       32

                                      LOGO
 
     The Company believes that, for certain applications, iontophoretic drug
delivery systems may offer several advantages over other drug delivery methods,
including:
 
     Broad Applicability. A substantial number of the drugs on the market and in
development today are, the Company believes, ionic and water-soluble and,
therefore, may be amenable to delivery by iontophoresis. In addition,
iontophoretic drug delivery systems may be applicable to a significantly broader
range of pharmaceutical compounds, including larger drug molecules such as
peptides and oligonucleotides, than passive transdermal drug delivery methods.
 
     Increased Convenience and Compliance. Iontophoretic drug delivery systems
are easy to use and offer simple, needle-free administration that eliminates the
inconvenience of frequent dosing, and may, if successfully developed and
approved by applicable regulatory authorities, permit patient
self-administration.
 
     Programmable Control of Drug Delivery. The rate, timing and pattern of drug
delivery using an iontophoretic drug delivery system can be controlled by
varying the electrical current applied to the system's electrodes. The benefits
of this ability to control the drug's delivery include the following:
 
     -  Rapid Onset of Action -- The speed with which a drug delivery system can
        provide efficacious blood levels of the target drug determines the onset
        of therapeutic action. Iontophoretic drug delivery systems allow many
        drugs to pass directly through the skin into underlying tissue and the
        bloodstream at a rate that is significantly more rapid than oral or
        passive transdermal delivery methods. Research has shown that certain
        drugs can be delivered by iontophoresis more than 10 to 1,000 times
        faster than drug delivery by passive transdermal patches.
 
     -  Rapid Cessation of Administration -- In certain applications, it is
        desirable that drug delivery cease once the desired effect has been
        obtained. Iontophoretic drug delivery systems allow rapid cessation of
        drug delivery since absorption of water-soluble drugs from the skin into
        bloodstream ceases rapidly after the current is turned off or the drug
        electrode is removed from the skin.
 
     -  Variable Dose Control -- Iontophoretic drug delivery systems may be
        designed to offer precision controlled dosing that can be customized for
        desired therapeutic profiles or for individual patient needs, including
        baseline and/or bolus dosing.
 
     -  Patient Controlled Dosing -- Iontophoretic drug delivery systems may be
        designed to offer active patient control or intervention in the dosing
        regimen, while at the same time incorporating programmed lock-outs for
        added safety and dose monitoring capability.
 
     -  Dose-to-Effect -- Iontophoretic drug delivery systems allow caregivers
        or patients to monitor the onset of drug effectiveness and maintain,
        progressively reduce or cease drug administration once a desired
        therapeutic effect is observed.

THE COMPANY'S IONTOPHORETIC SYSTEMS
 
     While the fundamentals of iontophoresis have been understood for decades,
the technology has become commercially practicable as a method for delivering
drugs only recently as a result of advances in electronics, materials science
and electrochemistry. These advances have led to the development of more
efficient and adaptable drug containment electrodes and more reliable, compact
and programmable dose controllers. The Company has developed iontophoretic drug
delivery systems which incorporate dose controllers and electrodes that have
enhanced performance characteristics, which the Company believes are adaptable
to a number of clinical settings and therapeutic applications, and which the
Company believes are cost effective in a number of therapeutic applications. The
Company's current iontophoretic drug delivery systems are not designed to
facilitate patient self-administration, but drug delivery systems currently
being developed by the Company may allow patients significant control over the
administration of certain drugs.
 
     In March 1997, the Company entered into an agreement with Elan to obtain an
exclusive, worldwide license to the commercial exploitation of certain
technology developed by Elan in the field of iontophoretic drug delivery and
certain other electro-transport fields. The acquisition of the Elan technology
is intended to speed the development and commercialization of products using the
combined technologies, including the miniaturized integrated, wearable systems
currently under development by the Company. The Company also believes its
competitive position in relation to other companies engaged in the development
of iontophoretic drug delivery systems has been significantly enhanced by Elan's
broad base of United States and foreign patents, in-depth body of in vitro drug
transport data and in vivo animal and human clinical data, in addition to other
proprietary know-how.
 
     Dose Controllers. The Company's dose controllers generate the low-level
electrical current needed for iontophoretic drug delivery. The Company presently
markets a compact, fully portable dose controller, the Phoresor, that offers
durable microprocessor control, enhanced user interface, versatile programmable
dosing capability, autocalculating treatment time (based on electrical current
settings and selected dose) and constant current output (by automatically
adjusting voltage to compensate for variations in the electrical resistance of
the skin). The Phoresor incorporates a microprocessor, other electronic
circuitry, on-board software that monitors and controls the rate of current
flow, and an easy-to-use control panel. The Company has also developed, and
anticipates marketing in the near future, a new dose controller for specific use
with its pediatric local dermal anesthetic product. See "Business -- Products
and Products Under Development -- Local Dermal Anesthesia." The Company's next
generation of dose controllers, both stand-alone and wearable miniaturized
versions, are being designed to include many of the same features as the
Company's current dose controllers. Depending on the therapeutic application,
the new generation dose controllers may be designed to allow bolus dosing
capability and programming (using a physician's or pharmacist's key) to adjust
dosing to match desired delivery profiles or patterns.
 
     In a clinical setting for short treatment durations, the battery and dose
controller are housed in a discrete, reusable, table-top unit connected to a
pair of disposable, single-use electrodes to which drug solution is added
immediately prior to application to the patient. This technology is used in the
Company's current products. For longer term or chronic applications or
patient-administered therapy outside the clinical setting, the Company is
developing iontophoretic drug delivery systems in which the battery, dose
controller and electrodes will be combined in a small patch applied to the skin
as a single, integrated unit. The electronic components may be reusable, with
replaceable or rechargeable batteries and single-use, disposable drug and
grounding electrodes, or the entire unit may be disposable after a single use.
The drug may be added to the electrode drug pad during manufacturing, or may be
stored separately in the system and introduced into the drug containment pad
immediately before use by means of proprietary, integrated hydration devices
developed by the Company.
 
     Electrodes. Electrode design is critical to successful delivery of a drug
by iontophoresis. The Company's electrodes incorporate patented and proprietary
design innovations which the Company believes offer significant advantages to
both patients and health care providers. The Company's proprietary electrode
technology includes patented polymer hydrogels which absorb drug solutions in
seconds, becoming soft and pliable so as to conform better to the body and to be
comfortable to the patient. The Company's electrode
 
                                       34
<PAGE>   36
 
technology also employs special silver and silver chloride inks to distribute
electric current evenly from the dose controller to the electrodes and control
possible changes in acidity and alkalinity (pH changes) which can occur during
iontophoresis, thereby preventing possible drug instability or unacceptable skin
irritation.
 
BUSINESS STRATEGY
 
     The Company's primary business goal is to establish its proprietary
iontophoretic drug delivery systems as a preferred, cost effective means of
delivering a wide range of drugs. To achieve this goal, the Company uses its
multi-disciplinary expertise in pharmacology and drug formulation, regulatory
and product testing, microelectronics, electrochemistry, polymer chemistry and
adhesives. The Company's strategy for achieving this goal includes the following
principal elements:
 
     Develop Systems for Off-Patent Drugs. The Company intends to continue the
independent development of proprietary iontophoretic drug delivery systems for
off-patent drugs with known safety and efficacy and for which the Company
believes its drug delivery technology may be cost competitive with and offer
advantages over other drug delivery methods. The Company believes that, by
developing proprietary products based on currently approved off-patent drugs,
rather than new chemical entities ("NCEs"), it can reduce regulatory and
development risks and shorten the product development cycle for certain
products. See "Risk Factors -- Uncertainty of Government Regulation" and
"Business -- Government Regulation."
 
     Enter into Collaborative Relationships. In order to gain access to NCEs and
other proprietary drugs, and to reduce the costs and risks associated with the
development of iontophoretic drug delivery systems for such compounds, the
Company intends to enter into collaborative relationships with pharmaceutical
and other biotechnology companies whose drugs could benefit from the Company's
iontophoretic drug delivery technology. The Company has entered into a
collaborative development agreement with Novartis for the purpose of evaluating
the potential for the development of iontophoretic drug delivery systems for a
number of Novartis compounds for several therapeutic applications. In
collaboration with Novartis, the Company is currently developing an
iontophoretic drug delivery system to deliver a drug for the treatment of
osteoporosis.
 
     Increase Market Penetration of Existing Products. In order to leverage the
capabilities of its direct and dealer sales forces, the Company intends to enter
into collaborative sales and marketing relationships with other parties that
have specific expertise in markets targeted by the Company. In general, the
Company intends to use collaborative sales and marketing relationships in the
sale and distribution of its products to the general physician, international
and specialty markets, including the podiatric, orthopedic and chiropractic
markets.
 
     In addition, the Company is actively seeking to expand the commercial
potential of its local anesthesia and acute inflammation products by pursuing
new applications. The Company will continue to conduct (i) marketing studies
aimed at expanding the use of its delivery system for Iontocaine to a broader
range of procedures and (ii) clinical trials to further establish the safety and
efficacy of iontophoresis for the treatment of local inflammation using
Dexamathasone or for use in other specific procedures.
 
     Broaden Technology Platform. The Company intends to enhance its proprietary
iontophoretic technology base principally through internal research and
development. The Company will also pursue additional iontophoretic and other
complementary products and technologies owned or developed by third parties, on
a case-by-case basis, through in-licensing or acquisition.
 
     Control Product Manufacturing Processes. The Company intends to maintain
control over the manufacture of its electrode kits in order to retain control
over the quality of its products and capture a larger portion of the product
revenue stream when third parties are involved in the marketing of the product.
 
PRODUCTS AND PRODUCTS UNDER DEVELOPMENT
 
     The Company currently has product development programs at various stages of
development for acute local inflammation, local dermal anesthesia, remission of
pre-term labor, conscious sedation, pain control and osteoporosis. The following

  ACUTE LOCAL INFLAMMATION
 
     Acute local inflammatory conditions resulting from exercise, sports
injuries, trauma or repetitive motion disorders are among the leading types of
injuries occurring in the workplace and among physically active adults. The most
common of these injuries include tendonitis, bursitis, carpal tunnel syndrome
and epicondylitis (tennis elbow). Generally, patients suffering from these
conditions are initially treated with oral nonsteroidal anti-inflammatory drugs
("NSAIDS") for a period of up to fourteen days. Although steroid injections are
generally more effective than NSAIDS, medical professionals usually avoid
steroid injections in all but severe cases because of the negative side effects
that can accompany bolus needle injections of corticosteroids into an inflamed
joint or tendon, including risk of infection, tissue distortion, tendon
weakening and tendon rupture. If patients do not respond to treatment with
NSAIDS, the physician generally has two options -- refer the patient to a
physical therapist, or proceed with injection of anti-inflammatory steroids such
as Dexamethasone. Based on market data with respect to the number of
corticosteroid injections for acute inflammation as well as data gathered by the
Company in a survey it conducted of 54 physical therapy clinics around the
United States with respect to the number of patients that visit physical therapy
clinics for acute inflammation, the Company estimates that the total potential
retail market in the United States for the sale of iontophoretic drug delivery
systems to clinicians to treat acute local inflammatory conditions is in excess
of $400 million. In addition, the Company estimates that current total retail
sales into this market by the Company and its competitors are under $30 million.
 
     The Company believes iontophoretic delivery of Dexamethasone provides
significant advantages over other current treatment regimens for acute local
inflammation. The Company believes iontophoresis eliminates many of the risks
and inconvenience associated with bolus steroid injections, avoids the systemic
side effects of oral steroids and eliminates the significant incidence of GI
tract side effects of orally
 
                                       36
<PAGE>   38
 
administered NSAIDS. The Company believes iontophoresis also increases
therapeutic efficacy by bypassing metabolism by the liver, by reducing the
possibility of overdosing, and by providing localized delivery at the target
site without trauma. As a result, the Company believes that it may be
advantageous to introduce the iontophoretic delivery of Dexamethasone into the
initial treatment regimen for acute local inflammation. The Company believes
that earlier treatment with Dexamethasone has the potential to significantly
increase the rate of patient recovery and, in doing so, reduce the overall cost
of patient treatment.
 
     Commercial Products. The Company pioneered the commercial introduction of
an iontophoretic drug delivery system for the treatment of local acute
inflammation in 1979. The product is used principally by physical therapists
(under a doctor's prescription) and has been administered in over 10 million
patient treatments for the iontophoretic delivery of Dexamethasone. More than 8
million of these treatments occurred since 1990, when advancements in electrode
technology made by the Company led to the introduction of its present family of
gel electrodes for use with its microprocessor controlled dose controller. The
Company's system for the delivery of Dexamethasone is also used by athletic
trainers and physical therapists serving a number of professional athletes,
including professional golfers and tennis players, men's and women's olympic ski
teams and professional football, basketball and hockey teams. The Company
believes that iontophoretic drug delivery systems are accepted in the
rehabilitation marketplace due to their ease of use, non-invasiveness,
recognized efficacy and lack of side effects.
 
     The Company currently markets four different electrode kits in three
different configurations and continues to develop additional electrode kits and
configurations for application in different segments of the acute local
inflammation market. The Company's existing electrode kits, as well as those it
has under development, are designed to be user friendly and to offer clinicians
a broad range of electrode sizes, formats, configurations and price ranges.
 
     Products Under Development. Currently, due to limited labeling of
Dexamethasone, neither the Company nor its competitors has the requisite
regulatory approval to specifically promote the use of iontophoretic drug
delivery systems for the delivery of Dexamethasone. The Company believes that
its inability to do so limits its ability to market its system, particularly to
the physician market. The Company further believes that to market iontophoretic
drug delivery systems for a specific drug and therapeutic indication the FDA
requires that each new drug/device combination be approved through an NDA
process. Therefore, in order to expand the Company's sales of its delivery
systems into the physician market as a first line treatment for acute local
inflammation, the Company has filed an investigational new drug ("IND")
application with the FDA under which it intends to establish the safety and
efficacy of its current drug delivery system for Dexamethasone. Upon completion
of the protocol design, the Company intends to select appropriate clinical sites
and initiate clinical studies in support of filing an NDA (or an appropriate
drug/ device combination marketing application seeking FDA approval to label a
formulation of Dexamethasone for use with the Company's Phoresor for treatment
of acute local inflammatory conditions. The Company believes that because of the
known safety and efficacy profile of Dexamethasone and the acute nature of the
conditions to be treated in these studies, the duration of the studies and the
required follow-up periods may not be as extensive as would be required for a
NCE. See "Risk Factors -- Uncertainty of Government Regulation."
 
     The Company believes the approval of an NDA (if obtained) will allow the
Company to actively promote the iontophoretic delivery of Dexamethasone to
general and family practice physicians, orthopedists, neurologists and sports
and industrial medicine clinics. The Company believes this could significantly
enhance the Company's ability to establish its delivery system for Dexamethasone
as a primary treatment option for acute local inflammatory conditions. The
Company also believes that, with an approved NDA to complement its device, many
physicians who refer their patients for physical therapy will do so with a
specific prescription for iontophoresis using the Company's proprietary drug
delivery system.
 
  LOCAL DERMAL ANESTHESIA
 
     Medical care providers have long recognized the importance of the
management of pain, including pain associated with certain minimally invasive
medical procedures such as needle injections; venous access (including
phlebotomies and intravenous catherizations); lumbar punctures; and local
dermatological,
 
                                       37
<PAGE>   39
 
gynecological and urological procedures such as wart and mole removal, LOOP/LETZ
procedures, biopsies (including fine needle, punch, excisional, shave and
cervical biopsies), Mohs procedures and vasectomies. To address this concern,
local dermal anesthetics are widely used in medical practice.
 
     The primary means of administering local dermal anesthetics is by needle
injection, which has the benefit of being fast, effective and long lasting.
However, the fear and pain associated with the needle stick, especially on the
extremities or on other sensitive areas such as the face, vulva and cervix is
compounded by the sting associated with virtually all injectable local
anesthetics. These factors increase patient discomfort and anxiety. In addition,
the local tissue distortion which typically accompanies injections may cause
procedural difficulty for the physician. New topical analgesic formulations have
recently been introduced into the market and are gaining widespread acceptance,
especially in pediatric hospitals and clinics and in pediatric dermatology.
These topical formulations avoid many of the pitfalls of anesthetic injections,
but they generally require significant advance preparation since they require
one to two hours to obtain anesthesia. Even when topical formulations are given
adequate time to achieve anesthesia, they anesthetize only to a maximum depth of
3 to 5 mm. The time required to achieve therapeutic anesthesia and the depth of
anesthesia make these formulations less suitable or impractical for many
potential applications. The Company believes that the growing interest in these
products, in spite of their clinical limitations, is a positive indication of
the market's desire for an effective, needle-free local dermal anesthetic.
 
     Commercial Products. The Company's Iontocaine brand of lidocaine HCl 2% and
epinephrine 1:100,000 is FDA approved under an NDA and is specifically labeled
for use with the Company's Phoresor and its proprietary, single use, disposable
electrode kits. The Iontocaine delivery system was shown to be safe and
effective in double blinded, placebo controlled, randomized studies in over 400
adult and pediatric patients. Based on these studies, the Company filed an NDA
with the FDA and received labeling to use the system for all procedures
requiring local dermal anesthesia.
 
     Using the Company's product, clinicians can administer needle-free, long
lasting (up to two hours) local dermal anesthesia up to a depth of 10 mm in
approximately ten minutes. The Company believes the ability to provide painless
local dermal anesthesia up to three times deeper than topical formulations, in
85% less time, could make the Company's products a preferred drug delivery
method for many existing applications where topical anesthetic creams are
currently employed, and that the product will provide a means of painlessly
inducing local dermal anesthesia for a broader range of medical procedures where
the use of such creams is not practical.
 
     A leading concern among patients, parents and health care professionals is
the control of pain in the practice of children's medicine, including the pain
associated with needle insertions. With the growing acceptance of topical
anesthetic creams in the pediatric hospital setting, the Company believes there
is a large potential market for an iontophoretic drug delivery system targeted
toward pediatrics. Accordingly, the Company has focused its initial local dermal
anesthesia product launch into the pediatric market under the brand name Numby
Stuff. Numby Stuff, which the Company launched in January of 1997, currently
consists of the Phoresor, the Company's line of proprietary, single use,
disposable electrode kits and Iontocaine, all in a brightly colored, child
friendly product package. Numby Stuff is currently being used to induce local
dermal anesthesia prior to pediatric intravenous starts, blood draws and other
invasive procedures, and the Company believes it provides a cost effective
alternative to the leading topical product. The Company estimates that pediatric
intravenous starts, blood draws and other invasive procedures are performed more
than 20 million times in the United States each year.
 
   
     At the Company's request, Numby Stuff was recently reviewed by the new
product review committee of the Alliance of Children's Hospitals ("ACH"), a
consortium of 36 free standing children's hospitals in the United States.
Following the review, in December 1996, the Company acquired a right from ACH to
use ACH's Seal of Acceptance in the commercialization of Numby Stuff. In order
to use the Seal of Acceptance to promote Numby Stuff, the Company was required
to make royalty payments to ACH. The Company satisfied ACH's royalty
requirements by issuing ACH warrants to acquire, through December 1, 2003,
44,791 Common Shares at an exercise price of $8.88 per share. In connection with
obtaining the rights to use the ACH Seal of Acceptance, and at the request of
the Child Health Investment Corporation ("CHIC"), an
    
 
                                       38
<PAGE>   40
 
   
affiliate of ACH, the Company sold CHIC 37,202 Common Shares for $250,000. CHIC
maintains a venture fund to make investments in medical products companies.
Under the terms of the Company's agreements with ACH, ACH is obligated to
provide continued support and endorsement for Numby Stuff and, although ACH's
member hospitals are not required to purchase any product awarded ACH's Seal of
Acceptance, ACH is obligated to assist the Company in introducing Numby Stuff to
pharmacy directors and other clinical specialties within its member hospitals.
    
 
     Products Under Development. The Company has developed a working prototype
of a preprogrammed, fixed dose, dose controller with push-button operation for
use as part of the Numby Stuff product. The Company is currently working with
its third party supplier to develop manufacturing specifications for the new
dose controller, and expects to initiate manufacturing and marketing of the dose
controller in fiscal 1998. The Company believes that the new dose controller's
anticipated pricing and simplified operation will further enhance the
marketability and use of Numby Stuff.
 
     In order to achieve greater market acceptance of its Iontocaine product in
pediatric markets, the Company supports evaluations conducted by doctors and
other medical personnel for the use of its anesthetic product prior to a wide
variety of painful medical procedures. The Company is currently conducting or
planning two studies evaluating the use of Numby Stuff prior to lumbar punctures
and circumcisions in pediatric patients. Depending on the results of these
studies, the Company may develop new electrode kits which specifically address
these opportunities. The Company also believes, in addition to the pediatric
market, the adult hospital market represents additional opportunities for
growth. The Company believes that it could service the adult hospital market by
making minor modifications in its product image and by using its existing sales
force. For example, according to published studies, there are over 250 million
venous catheters inserted each year, of which a large percentage are inserted in
adult patients.
 
     The Company also believes Iontocaine, together with the Phoresor and
adaptations of its existing electrode designs, can be successfully used to
induce effective local dermal or mucosal anesthesia prior to certain
gynecological procedures. The Company believes the effective, rapid, painless,
needle-free anesthesia provided by the Company's drug delivery technology would
increase patient comfort. In general, the Company believes the promotion of the
Company's systems for use in connection with gynecological procedures involving
mucosal membranes would require additional FDA approval, most likely in the form
of a supplement to the Company's existing Iontocaine NDA. The Company does not
believe gynecological procedures involving the vulva would require additional
FDA approval. The Company has performed preliminary studies which indicate that
its anesthetic system may significantly reduce or eliminate the pain of vulvar
biopsies. The Company has already tested prototype electrodes which are
specifically designed for this application. There are approximately 50 million
pap smears performed each year in the United States, of which the Company
estimates approximately 2.5 million require follow-up procedures that could
benefit from non-invasive local dermal anesthesia. The majority of these
procedures are performed by a relatively small number of gynecologists who are
mainly located in high density population areas that are also the major centers
for the Company's pediatric marketing efforts. See "Risk Factors -- Uncertainty
of Government Regulation."
 
  REMISSION OF PRE-TERM LABOR
 
     Pre-term birth is a leading cause of neonatal morbidity and mortality. Each
year in the United States alone, 10% of all births are premature resulting in
more than 400,000 babies being born before completing 37 weeks of gestation. The
cost of neonatal intensive care required for pre-term babies exceeds $5.0
billion a year in the United States. The Company believes prolonging pregnancies
threatened by pre-term delivery by even a few days may result in improved
clinical outcomes, which could represent an important opportunity for
significant medical, economic and social benefits.
 
     The Company estimates that each year a significant number of patients in
the United States who are at risk for or experience pre-term labor and pre-term
birth are placed on one or more forms of tocolytic drug therapy. Tocolysis is
the clinical term for the remission of labor. Although many of these therapies
are not specifically FDA approved, the medical literature indicates that they
have been successful in a large number of patients. The Company believes the
number of patients placed on various tocolytic drug therapies will rise
 
                                       39
<PAGE>   41
 
with the increased use of ambulatory external tocodynamometers and the advance
of other new diagnostic techniques and products used to identify patients at
risk. These advances in diagnostics should aid in identifying asymptomatic
pregnant women.
 
     A typical therapeutic program for a pregnant woman who is experiencing
acute episodes of pre-term labor consists of intravenous ("IV") infusions of
magnesium sulfate in the hospital. After a period of 12 to 24 hours of
successful tocolysis, the patient is then switched to oral terbutaline sulfate
tablets and released. Usually, after two to three weeks, the therapeutic effects
of oral terbutaline are lost and the patient must be readmitted to the hospital
to begin the treatment cycle again. If symptoms persist, the patient is often
placed on an injectable form of terbutaline sulfate by means of a subcutaneous
infusion pump. Although not approved by the FDA for this indication,
subcutaneous infusion terbutaline therapy has been found to be effective in
controlling pre-term labor and avoiding the loss of therapeutic efficacy
experienced with oral dosing. Subcutaneous infusion terbutaline therapy can last
for a over a month, with a mean treatment period of approximately three weeks,
and costs approximately $1,500 to $2,000 per week. Those costs include pump
rental, drugs, disposable infusion kits and central monitoring and home visits
by a skilled medical professional.
 
     Products Under Development. The Company is evaluating a system for
delivering terbutaline using iontophoresis. Based on in vitro feasibility
testing it has conducted, the Company believes terbutaline may be delivered by
iontophoresis in therapeutic quantities. The Company intends to seek NDA
approval for the delivery of terbutaline for remission and pre-term labor using
its iontophoretic drug delivery system. It has prepared a protocol for a Phase I
blood level study, has received Institutional Review Board approval and expects
to initiate that study by the end of 1997. The Company believes that an
iontophoretic drug delivery system for terbutaline could offer an alternative
treatment regimen to oral terbutaline therapies with all of the benefits of home
infusion therapy. The Company also believes an iontophoretic system may have
substantial advantages over subcutaneous infusion therapy, including being less
expensive to produce and service than standard infusion therapy devices,
potentially providing greater patient comfort (since the electrodes could be
placed at various sites on the body) and being non-invasive, thereby eliminating
the risk of infection and reducing the need for frequent intervention by a
skilled medical professional.
 
     Since the general pharmacology and toxicology of terbutaline are well
known, and because the Company believes this is an area of significant interest
within both the FDA and the medical community, the Company believes that, if its
Phase I blood level studies are successful, it may be able to progress more
rapidly into Phase III studies in at-risk, pregnant women than would be possible
for an NCE. Due to the nature of the condition being treated, the Company
believes the clinical trials should be of relatively short duration and will
have a clearly defined endpoint. See "Risk Factors -- Uncertainty of Government
Regulation."
 
  CONSCIOUS SEDATION
 
     Many patients, especially children, experience extreme anxiety before the
start of invasive or painful medical procedures, during stressful diagnostic
tests such as endoscopies, magnetic resonance imaging, and CT scans, and before
and during certain dental and emergency room procedures. Invasive methods of
premedication and sedation, such as intramuscular ("IM") injections or IV
administration of analgesics or sedatives, can cause anxiety. Clinicians have
long sought alternative, non-invasive methods of premedication. Despite the
absence of approved labeling for safety and efficacy for oral administration,
clinicians widely use injectable drugs and drug combinations mixed with flavored
syrups for off-label oral administration in children. Since 1994, clinicians
have also been able to use fentanyl for conscious sedation using an oral
transmucosal delivery system. Oral administration may require up to five times
the amount of drug recommended for injection because of decreased
bioavailability, but is used because the alternative of IV or IM injections are
counterproductive to the goal of relieving anxiety. Based on market data, the
Company estimates that annual worldwide sales of the top two products used for
conscious sedation are approximately $950 million.
 
     Products Under Development. The safety and efficacy of fentanyl as a drug
to induce conscious sedation are well known. Data from two human blood level
studies with fentanyl conducted by the Company and a former collaborative
partner show that it may be possible for therapeutic quantities of fentanyl to
be delivered
 
                                       40
<PAGE>   42
 
by iontophoresis. Therefore, the Company believes it could represent a viable
drug for inducing conscious sedation using the Company's iontophoretic drug
delivery systems. As a result of an existing contractual obligation with its
former collaborative partner, the Company has agreed not to pursue development
of a fentanyl conscious sedation product until the second quarter of calendar
year 1998. Further, the Company's ability to market a product in the United
States using fentanyl may also be limited by certain litigation now before the
PTO. See "Risk Factors -- Dependence on Patents and Proprietary Technology" and
"Business -- Collaborative Relationships and Licenses."
 
  PAIN MANAGEMENT
 
     The Company estimates that of the 24 million surgeries performed each year
in the United States, 75%, or 18 million, result in moderate to severe post
operative pain. In addition, there are currently 9.1 million cancer patients in
the United States. Each year roughly 6.6 million patients with cancer are
treated for pain and of these 65% to 80%, experience moderate to severe pain. In
recent years, there has been a growing awareness that many patients, especially
the terminally ill, do not receive adequate analgesic therapy for their pain.
Sales of prescription narcotics in the United States to treat pain were
approximately $1.0 billion in 1996 and according to market reports the market is
estimated to grow at a rate of approximately 10.5% per year. Factors
contributing to this growth rate include more relaxed policies for narcotic
administration and the introduction of drug delivery systems that make
administration safer, more controllable and convenient.
 
     Morphine is the most commonly prescribed drug for the management of severe
pain in critically ill patients in the United States. Morphine and hydromorphone
are the most widely used parenteral pain medications for home use because they
are relatively safe, effective and have relatively short half lives.
Hydromorphone is a more potent, highly soluble analog of morphine, which is the
standard against which other analgesics are generally measured.
 
     The Company believes that iontophoretic delivery systems for narcotic
analgesics for the treatment of post operative and chronic pain control could
offer significant benefits over existing methods of delivery, including infusion
pumps, transdermal patches and transmucosal products. To provide effective pain
relief, a morphine injection is generally administered every four hours.
Repeated injection or continuous infusion of morphine is expensive because the
methods of administration consume substantial hospital staff time or require
daily visits by a health care provider to a patient receiving home infusion
therapy. An iontophoretic system has the potential to offer all of the benefits
of an infusion pump, including the ability to closely match the delivery profile
with rapid onset and cessation of action characteristics and to provide control
of baseline delivery with bolus dose capability for acute episodes of pain, but
without the need to use needles. The Company believes an iontophoretic delivery
system for pain management may also be more convenient and less expensive, since
the rental of costly infusion pumps and intervention by a skilled medical
professional may not be required. Passive transdermal patches offer convenience
and reduced costs, but they take four to eight hours before effective analgesia
is achieved and take hours or even days for the drug depot to clear from the
skin after the patch is removed. In addition, passive transdermal patches do not
offer precise baseline dosing from patient to patient and do not address the
need for bolus dosing required to address acute episodes of pain.
 
     Products Under Development. The Company believes an iontophoretic delivery
system for hydromorphone may be a favorable alternative to the administration of
morphine by infusion for acute post operative pain and for chronic pain in the
hospice or home care setting. Hydromorphone is approximately ten times more
potent than morphine and has added therapeutic advantages, including lower
incidence of nausea and vomiting (which frequently accompanies the
administration of morphine), and more effective analgesia with no stupefying and
minimal hypnotic effects. Through the Elan Agreements, the Company obtained
rights to prototype wearable iontophoretic drug delivery systems for the
delivery of hydromorphone and to the preclinical, Phase I and limited Phase II
clinical data generated by Elan in testing the device. The Company believes the
additional clinical trials necessary to market this product may be of relatively
short duration in comparison to an NCE, since hydromorphone's safety and
efficacy profile is well known and the clinical endpoints are both well
established and easy to measure. See "Risk Factors -- Uncertainty of Government
Regulation."
 
                                       41
<PAGE>   43
 
     In addition to a system for the delivery of hydromorphone, the Company
believes a market exists for an iontophoretic drug delivery system for fentanyl,
a narcotic analgesic more potent than hydromorphone, which has been used
primarily during surgery. The Company conducted a preliminary blood level study
using fentanyl and, using data from that study, designed advanced electrodes
which a former collaborative partner used in a subsequent fentanyl human blood
level test. These studies demonstrated that fentanyl can be delivered by
iontophoresis to achieve the delivery rates and blood levels necessary for pain
control.
 
     Due to its short half-life in the body, injectable fentanyl is not
generally used for the treatment of moderate to severe post-operative or chronic
pain. However, the increased use of home infusion therapy and the development of
a passive transdermal patch have demonstrated that fentanyl can be delivered at
therapeutic levels, making the drug suitable for new indications not previously
possible with injections. The Duragesic transdermal fentanyl patch, which was
developed by Alza and is marketed by Janssen Pharmaceuticals, was introduced in
1992 and had annual worldwide sales of $205 million in 1996.
 
     As a result of an existing contractual obligation with its former
collaborative partner, the Company has agreed not to pursue development of a
fentanyl pain product until the second quarter of calendar year 1998. Further,
the Company's ability to market a product using fentanyl in the United States
may be limited by certain litigation before the PTO. See "Risk
Factors -- Dependence on Patents and Proprietary Technology" and
"Business -- Collaborative Relationships and Licenses."
 
  OSTEOPOROSIS
 
     Osteoporosis is a progressive disease that affects more than 25 million
people in the United States, most commonly post-menopausal women. The financial
costs associated with osteoporosis exceed $10 billion each year. Novartis and
the Company believe the overall therapeutic profile of the osteoporosis drug
currently under development may be optimized or enhanced through the use of an
iontophoretic drug delivery system. As a result, they have entered into an
agreement for the development by the Company of an iontophoretic drug delivery
system using the drug for the treatment of osteoporosis. The drug is currently
scheduled to enter Phase I clinical trials in 1998. See
"Business -- Collaborative Relationships and Licenses."
 
  OTHER POTENTIAL PRODUCT APPLICATIONS
 
     The Company has an active program of identifying and developing
iontophoretic drug delivery products for various therapeutic indications where
the Company believes there is a potential market need, where a suitable
water-soluble ionic drug is available and where that drug can be delivered
through iontophoresis in therapeutic quantities on a cost-competitive basis. The
Company has identified certain drugs and therapeutic indications as potential
product opportunities, and has undertaken preliminary steps toward verifying the
market need and technical feasibility of iontophoretic delivery of those drugs.
In addition, through the Elan Agreements, the Company acquired certain
in-process research and development, including exclusive world-wide rights for
the commercial exploitation of certain iontophoretic patents, know-how and
clinical data. The Elan technology includes in vitro feasibility studies
conducted on 64 drugs (including several peptide drugs), in vivo blood level
animal studies on 18 of those drugs and human blood level studies on nine of
those drugs. See "Business -- Products and Products Under
Development -- Osteoporosis."
 
     As part of its continuing product development program, the Company will
evaluate the feasibility of iontophoretic delivery of biotechnology derived
peptides, small proteins and oligonucleotides for applications where existing
drug delivery systems have significant limitations. The Company also intends to
examine the use of its iontophoretic system to deliver anti-emetics to treat
postsurgical nausea and vomiting induced by or secondary to chemotherapy,
surgery, migraine headache or AIDS.
 
COLLABORATIVE RELATIONSHIPS AND LICENSES
 
     A principal component of the Company's commercial strategy is to develop
products, where appropriate, in collaboration with established pharmaceutical
companies or other strategic partners. These collaborative partners may provide
proprietary drugs, technology, financial resources, research and pharmaceutical
manufacturing capabilities or marketing infrastructure to aid in the development
and commercialization of the
 
                                       42
<PAGE>   44
 
Company's products and potential future products. Depending on the availability
of financial, marketing and scientific resources and other factors, the Company
may also license or cross license its technology or products to others and
retain profit sharing, royalty, manufacturing, co-marketing, co-promotion or
similar rights. Any such arrangements could limit the Company's flexibility in
pursuing alternatives for the development or commercialization of its products.
 
     The Company has entered into the following collaborative relationships and
license arrangements:
 
     Novartis Agreement. In July 1995 as amended in March 1996, the Company
entered into various research and development agreements (the "R&D Agreements")
with the ethical pharmaceuticals division of Ciba-Geigy Corporation ("Ciba") to
evaluate the feasibility of delivering a number of Ciba compounds for several
therapeutic applications utilizing the Company's iontophoretic drug delivery
technologies, including certain of its existing iontophoretic devices. In
connection with the R&D Agreements, the Company formed Dermion to conduct the
Company's iontophoretic drug delivery research and development activities other
than those relating to the Company's current products, and Ciba then acquired a
20% equity interest in Dermion. In 1997, Ciba was merged with Sandoz Corporation
to form Novartis Pharma A.G.
 
     Under the 1997 Amendments, effective November 1, 1997, Novartis exchanged
its 20% equity interest in Dermion for 238,541 Common Shares and warrants to
acquire an additional 18,750 Common Shares at an exercise price of $21.60 per
share. Novartis may currently exercise one-third of the warrants, and will
obtain the right to exercise an additional one-third of the warrants in each
instance, when it agrees to provide research and development funding at a
minimum level of $1.5 million per year under the R&D Agreements for each of the
calendar years 1999 and 2000. The warrants, once exercisable, may be exercised
at any time through November 1, 2002.
 
     In connection with the R&D Agreements, the Company and Dermion granted
Novartis perpetual non-exclusive, royalty bearing licenses to the Company's
iontophoretic technology. Further, other than in collaboration with Novartis,
the Company has agreed that, during the term of the agreement (and, under
certain circumstances, for a period of up to two years thereafter), the Company
will not develop any product in certain Novartis fields, as defined in the
agreement, without Novartis' consent.
 
     Pursuant to the R&D Agreements, as amended, Novartis will provide Dermion
with research funding through December 31, 1998 for the continued development of
proprietary iontophoretic drug delivery systems to deliver Novartis compounds
and has the option to renew the research and funding for successive one year
periods. Presently, Dermion is devoting the majority of its research and
development efforts to the development of these systems and products for
Novartis compounds. One of the compounds covered by the R&D Agreements is
scheduled to enter Phase I clinical trials during 1998. The R&D Agreements may
be terminated by Novartis or the Company at any time on at least six months'
notice.
 
     The R&D Agreements, as amended, require Novartis to pay Dermion milestone
payments in connection with products developed for Novartis by Dermion, based on
the successful completion of certain later stage development objectives.
Additionally, Novartis is required to pay Dermion royalties on sales by Novartis
of products and systems developed by Dermion. No such sales have yet occurred
and no royalties have been received by Dermion.
 
     The Company has also agreed that, during the term of the agreement with
Novartis and for a period of five years thereafter, the Company will negotiate
in good faith to license to Novartis rights to any iontophoretic drug delivery
technologies developed or acquired by the Company but which are not covered
under the existing license agreements (the "Second Generation Technology").
Further, the Company has agreed to negotiate such additional licenses prior to
entering into any agreement to license or otherwise transfer any rights to such
Second Generation Technology to a third party. Under the 1997 Amendments, the
parties agreed to treat the Elan technology acquired by the Company as Second
Generation Technology. Accordingly, the Company intends to negotiate with
Novartis to license such technology to Novartis prior to initiating efforts to
negotiate any rights to such technology with any third party. Under the R&D
Agreements, as amended, the parties agreed that they will jointly own the
technology developed in the collaboration.

     The Company's agreements with Novartis contain contractual restrictions on
any change of control of Dermion (either through the sale of IOMED's stock in
Dermion or through the sale by Dermion of its securities, assets or business).
Through March 1998, any such change of control is prohibited and, during the
remaining term of the R&D Agreements, and for one year thereafter, Novartis has
a right of first offer to purchase Iomed's interest in Dermion or the assets of
Dermion in the event of any proposed change of control of Dermion. The right of
first offer does not extend to any overall change of control transaction
involving IOMED, such as the sale by IOMED of its securities or assets, or a
merger or consolidation. See "Risk Factors -- Reliance on Collaborative
Partners."
 
     Elan Agreements. Effective March 1997, the Company entered into the Elan
Agreements. Under the Elan Agreements, the Company acquired exclusive, worldwide
licenses to certain of Elan's iontophoretic drug delivery technologies,
including know-how and over 250 issued and 47 pending United States and foreign
patents. In exchange for those rights, the Company paid Elan $15.0 million
through the issuance to Elan of the Elan Notes, issued Elan warrants to
purchase, through December 1, 2003, 104,166 Common Shares of the Company at a
price of $21.60 per share, and agreed to pay Elan a royalty on net revenues
derived by the Company from the licensing or sale of its products. See
"Transactions Related to the Offering" and "Certain Transactions."
 
     Alza Agreement. Alza has developed competitive iontophoretic drug delivery
technology and is, by its published reports, undertaking to develop products
that may be competitive with the Company's products. As a result of the
uncertainty of the Company's and Alza's respective patent rights for certain
iontophoretic delivery technologies, in 1993, the Company entered into a
cross-license agreement with Alza. Under the agreement, the companies, among
other things, exchanged non-exclusive, royalty free rights to certain patented
technologies which each party believed to be of significant strategic importance
to the potential technological success of many iontophoretic drug delivery
applications. One patent sublicensed by Alza to the Company under the agreement
bears a nominal royalty rate if used. Both parties are prohibited from assigning
their rights under the agreement to certain named companies or any other entity
that derives more than 50 percent of its income from the development, licensing
and/or sale of drug delivery systems to other pharmaceutical companies without
first receiving the consent of the other party. Restrictions imposed on the
Company's ability to assign its rights under this agreement may have the effect
of prohibiting a sale of the Company to such named companies, or may otherwise
limit the Company's ability to capitalize on the commercial and other economic
potential of these technologies. The Company does not believe these restrictions
inhibit its existing business development strategy. See "Risk
Factors -- Anti-Takeover Provisions of the Company's Articles of Incorporation;
Utah Law and Certain of the Company's Agreements."
 
     University of Utah Agreement. In 1974, the Company entered into a licensing
agreement with the University of Utah Research Foundation (the "University").
Under the agreement, which was amended in 1993, the Company obtained an
exclusive license to certain iontophoretic drug delivery and prosthetic
technologies developed at the University. Under the terms of the amended
license, the Company is obligated to pay the University a royalty on all sales
of its iontophoretic drug delivery products through the year 2007. In December
1996, the Company sold the assets comprising its prosthetic technologies
operations to Fillauer, Inc. and, in connection with that sale, sublicensed its
rights in the prosthetic technologies covered by the license to Fillauer, Inc.
 
     Fillauer Agreements. Prior to January 1997, the Company provided
state-of-the-art prosthetics products to amputees throughout the United States,
Canada and Western Europe through its Motion Control division. Motion Control's
principal products were the Utah Artificial Arm and the ProControl II advanced
myolectric prostheses for above and below the elbow amputees.
 
     In December 1995, the Company sold the assets of its prosthetics
technologies operations to Fillauer, Inc. for $1.0 million and granted Fillauer
an exclusive, worldwide license and sublicense to the patents, trademarks,
know-how and other intellectual property of the Company relating to its
prosthetics products. Under the terms of the sublicense agreement, the Company
will receive license fees and royalties on future sales of such products.
 
                                       44

     Laboratoires Fournier Agreement. In July 1993, the Company entered into an
agreement with Laboratoires Fournier, a private French pharmaceutical company,
for the joint research and development of wearable integrated iontophoretic
systems, with primary effort devoted to the development of systems for the
treatment of acute post operative pain and patient controlled analgesia. The
companies subsequently concluded that certain United States patents issued to
Alza for the iontophoretic delivery of fentanyl and its analogs after the
Company and Laboratoires Fournier had entered into their agreement posed a
potential barrier to the commercial viability of the proposed system in the
United States. As a result, the Company elected to suspend development efforts
in the area. In February 1996, the parties terminated their collaborative
research and development activities and amended their initial agreement. In
connection with the termination of their collaborative efforts the Company
issued Laboratoires Fournier 337,837 Common Shares in satisfaction of a $3.0
million loan Laboratoires Fournier had made to the Company. Under the amended
agreements, both companies have rights to all jointly developed iontophoretic
technologies and know-how, and Laboratoires Fournier has a limited non-exclusive
license to the Company's previously existing proprietary iontophoretic
technologies. The Company also agreed not to pursue development of delivery
systems for systemic pain control, including conscious sedation and pain
management, for a two year period ending February 1998.
 
     Boston University Agreement. In December 1997, the Company acquired a
non-exclusive, fully-paid, perpetual, non-royalty bearing license to certain
iontophoretic drug delivery technology developed by Boston University. The
agreement also provides the Company with the right to sublicense the technology
upon the payment of a sublicense fee.
 
MANUFACTURING
 
     The Company manufactures, tests, inspects, packages and ships its products
from an approximately 18,000 square foot leased manufacturing facility located
in Salt Lake City, Utah. The Company's manufacturing activities primarily relate
to its manufacture of electrode kits. The Company does not manufacture or
repackage any drugs or compounds used in its delivery systems and outsources the
manufacture and assembly of its Phoresor dose controllers.
 
     The Company and certain of its suppliers are required to comply with FDA
regulations governing manufacturing practices, including the Quality System
Regulation, which mandate controls for product design, control and quality. The
Company believes it is in compliance with the Quality System Regulation. The
Company recently received its ISO 9001 and CE Mark certifications, which are
standards imposed by certain European countries on drug and medical devices
manufacturers. The Company has good manufacturing practices audits conducted on
a regular basis.
 
     Manufacture of Electrodes. The Company's iontophoretic drug delivery
electrode kits are manufactured and assembled using several proprietary
materials, processes and production technologies developed by the Company in
conjunction with its equipment and material suppliers. The Company assembles its
electrodes from internally manufactured components and outsourced components
that are manufactured by third parties to the Company's specifications. Each of
the Company's existing electrode kits is assembled on a separate production
line. The key components of the Company's electrodes are the rehydratable drug
containment pads (which use either the Company's multi-laminate hydrogel or its
gel sponge technologies), and silver and silver/silver chloride conductive
elements.
 
     The Company manufactures the rehydratable drug containment pads used in its
electrodes. These pads are manufactured, using the Company's proprietary
processes, from multiple layers of a polymer material or from a sponge material
impregnated with a hydrogel. The silver and silver/silver chloride conductive
elements used in the Company's electrodes are manufactured for the Company to
its specifications by a third party. The Company has manufactured internally all
of the electrodes it has sold, and believes its electrode manufacturing capacity
can be expanded to meet its needs for the foreseeable future.
 
     The Company has adopted a "team" approach on its electrode assembly lines
and, by changing the production flow process and automating certain production
steps, was able to reduce manufacturing personnel from 70 in 1992 to 26 persons
in 1997, thereby reducing per unit production costs while increasing product
 
                                       45
<PAGE>   47
 
lines and production levels. The Company intends to use a portion of the
proceeds of the Offering for capital equipment to further automate the assembly
and packaging of the Company's electrodes, to increase capacity and to reduce
costs. See "Use of Proceeds."
 
     Manufacture of Dose Controllers. The Company's patented Phoresor
iontophoretic dose controllers employ a variety of sub-assemblies and components
that are designed or specified by the Company, including certain
microprocessors, circuit boards, on-board software, electrical lead wires and
control panels. These components and subassemblies are typically manufactured
for the Company by third parties, which then ship them to a contract
manufacturer for final assembly, testing and inspection in accordance with the
Company's specifications. The Company's manufacturing activities for the
Phoresor dose controllers are limited to design, labeling, inspection and
packaging.
 
     The Company's second and third generation dose controllers are in various
stages of design, research, and development and may require additional clearance
or PMA approval from the FDA prior to marketing. The Company, alone or in
conjunction with its development partners, will design the products and, in
combination with its suppliers, will manufacture and assemble prototypes and
clinical quantities. Upon completion of the design, specifications and testing,
the Company intends to subcontract the manufacture and assembly of all
commercial quantities of its dose controllers to electronics companies that
specialize in such work. See "Risk Factors -- Uncertainty of Government
Regulation."
 
     The Company purchases certain components and materials used in its products
from single source suppliers pursuant to existing purchase orders and
agreements. See "Risk Factors -- Dependence on Single Sources of Supply."
 
SALES AND DISTRIBUTION
 
     The Company's marketing strategy is to position its proprietary
iontophoretic drug delivery products in the marketplace as the preferred means
of drug delivery for a wide range of drugs. The strategy employs the use of
multiple sales and distribution channels, including (i) a network of medical
supply dealers; (ii) a direct sales force; and (iii) collaborative marketing
partners. The Company intends to use these distribution channels, both singly
and, for certain products, in combination, to maximize the Company's marketing
resources.
 
     Local Inflammation Products. The Company has historically targeted its
sales efforts for its drug delivery system for acute local inflammatory
conditions to the rehabilitative medicine, physical therapy and related
specialty markets. The Company employs a nationwide distribution network
consisting of approximately 50 durable medical equipment and physician supply
dealers to sell and distribute its products in those markets. This dealer
network is supported by the Company's six regional sales managers and four
internal customer service representatives. In addition to the Company's sales
and distribution efforts for its local inflammation products in the United
States, it maintains marketing and sales activities in international markets,
including Europe, Scandinavia, Australia, South Korea, Singapore and Hong Kong.
These sales are made primarily through independent distributors operating in
those countries.
 
     The Company intends to expand its marketing efforts by expanding and
improving its existing product lines and expanding its sales and distribution
capabilities into new segments of the inflammation market (including the
podiatry, chiropractic and primary care physician markets) through the use of
additional specialty dealers. In order to enhance its marketing efforts, the
Company is pursuing an NDA for its acute local inflammation drug delivery system
for Dexamethasone. The Company believes an NDA, if approved, will allow it to
actively promote this product and will enhance the Company's ability to
establish the Dexamethasone product as a primary treatment option for acute
local inflammation conditions.
 
     Local Dermal Anesthetic Products. In 1997, the Company launched an
iontophoretic drug delivery system for Iontocaine. The Company has initially
targeted its sales efforts for the product in the pediatric hospital market
under the name Numby Stuff. In order to access this market, the Company intends
to hire a direct sales staff of approximately 40 persons over the next four
years to market Numby Stuff. To date, the Company has hired and trained seven
sales agents, and intends to hire and train the remaining 33 sales
 
                                       46
<PAGE>   48
 
representatives by the end of 1999. There can be no assurance the Company will
be able to recruit and hire such personnel successfully within such time frame,
or at all. The Company also intends to expand its marketing efforts for its
Iontocaine products for other applications and to the general physician office
and international markets through the use of collaborative marketing partners.
In addition, under the terms of the Company's agreements with ACH, ACH has
agreed to assist the Company in introducing Numby Stuff to pharmacy directors
and other clinical specialties within ACH member hospitals. ACH has also agreed
to provide the Company with other marketing and sales assistance, including
access to certain marketing data developed by ACH.
 
     Products Under Development. The Company is developing a number of
iontophoretic drug delivery systems for other therapeutic indications, including
remission of pre-term labor, conscious sedation, post operative and chronic pain
control and osteoporosis. If any of these products is successfully developed and
approved by the FDA, the Company would market those products in the hospital
market through its direct sales force and to the physician office, international
and other specialty markets through one or more collaborative marketing
partnerships.
 
PATENTS AND PROPRIETARY RIGHTS
 
     The Company's iontophoretic drug delivery technologies include patents,
trademarks, trade secrets and other proprietary know-how. These technologies are
used in various combinations in the testing, evaluation and formulation of
optimal ionic drug solutions and in the research, development, design and
manufacture of microprocessor controlled power supplies and iontophoretic
electrodes which are specifically designed and constructed for particular
therapeutic applications.
 
     The Company has implemented a policy of actively patenting and maintaining
as trade secrets and proprietary information all inventions and technologies
which it believes are important to its business operations. The Company
generally seeks patent protection for its key proprietary technologies and
technological products in the United States, Canada, Europe and Japan. The
Company also relies on a number of trade secrets, know-how, continuing
technological innovations and licensing opportunities to develop and maintain
its competitive position. The Company's patent committee meets regularly to
review and make recommendations to the Company's management regarding patent and
invention issues.
 
     As of October 1, 1997, the Company held or had rights to utilize 60 United
States patents and 245 foreign patents relating to its iontophoretic drug
delivery technology, and has (or has the rights to utilize) 15 pending patent
applications in the United States and 47 pending patent applications in foreign
countries for that technology. The Company also owns or has licensed rights to
three issued and one pending United States patent governing the design and
manufacture of certain myoelectric prosthetic devices, including the Utah
Artificial Arm, which it has sublicensed to a third party in connection with the
sale of the Company's Motion Control division in December 1996. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."
 
     The medical products industry has recently seen extensive litigation
regarding patents and other intellectual property rights. Intellectual property
litigation is expensive and time consuming and, if decided adversely to a party,
can result in substantial loss or diversion of revenues for, and could have a
material adverse effect on the business operations of, the losing litigant.
There can be no assurance the pending patent applications filed by the Company
will be approved by appropriate governmental agencies, or that the Company's
issued or pending patents will not be challenged or circumvented by its
competitors. There can also be no assurance the Company will not become a party
to intellectual property right litigation and its concomitant adverse effects.
Further, there can be no assurance infringement claims will not be asserted by
other parties in the future against the Company, or that, in such event, the
Company would prevail or be able to obtain licenses on reasonable terms if it
did not prevail in those infringement claims. Adverse determinations in any
litigation could subject the Company to significant liabilities and/or require
the Company to obtain licenses from third parties. If the Company is unable to
obtain necessary licenses or is unable to develop or implement alternative
technology, it could be unable to manufacture and sell the affected products.
Any of
 
                                       47
<PAGE>   49
 
these outcomes could have a material adverse effect on the Company's business
financial condition and results of operations.
 
     In August of 1993, the PTO issued a patent to Alza relating to the
iontophoretic delivery of fentanyl. Alza's subsequent patent request in Europe
has been denied, and its United States patent was reexamined by the PTO. In the
reexamination, all of the substantive claims that Alza made in the original
patent relating to fentanyl and its analogs were denied. Alza has appealed the
PTO's decision and, as a result, there can be no assurance Alza will not regain
its patent position. If Alza is successful in its appeal of the PTO's decision,
and if the Company proceeds in the development of an iontophoretic fentanyl
product, the Company may be required to obtain a license from Alza Corporation
to market an iontophoretic drug delivery system for fentanyl in the United
States. There can be no assurance the Company would be able to obtain a license
on terms which are acceptable to the Company, if at all. See "Risk
Factors -- Dependence on Patents and Proprietary Technology."
 
     In addition to its patented technology, the Company relies on trade
secrets, technical know-how and continuing invention to maintain its competitive
position and products. The Company works actively to foster continuing
technological innovation by its employees and consultants in order to maintain
its competitive position, and has taken security measures to protect its trade
secrets and periodically explores ways to further enhance its trade secret
security. The Company requires each of its employees and consultants to execute
an intellectual property and invention agreement. The agreement generally
provides that all inventions, designs, formulas, works of authorship,
compositions of matter and discoveries made, conceived of or developed by the
individual and all confidential information disclosed or made know to the
individual during the term of his or her relationship with the Company will be
assigned to and remain the exclusive property of the Company and that it will be
maintained as confidential and not disclosed to third parties at any time except
under specified circumstances. The agreements also prohibit the employee or
consultant from directly or indirectly competing with the Company during the
term of their relationship with the Company and from recruiting the Company's
employees on behalf of competitors after the termination of that relationship.
There can be no assurance these measures will provide adequate protection for
the Company's trade secrets or other proprietary information. There can also be
no assurance the Company's competitors will not independently develop
substantially equivalent proprietary information and techniques or otherwise
gain access to the Company's trade secrets.
 
     The Company engages in a number of collaborative relationships with third
parties. Under the terms of these relationships, the Company has agreed to act
as the licensor or licensee of certain technology and to engage in a number of
research and development activities relating to that technology or to the
development of iontophoretic drug delivery systems. Under these arrangements,
Alza and Laboratoires Fournier have obtained licenses to certain of the
Company's proprietary iontophoretic technologies. These companies will compete
with the Company for contracts with collaborative partners and are independently
developing iontophoretic drug delivery systems that will compete directly with
many of the products currently being developed by the Company. See "Risk
Factors -- Reliance on Collaborative Partners," "Business -- Collaborative
Relationships and Licenses" and "Business -- Competition."
 
GOVERNMENT REGULATION
 
     The research, development, manufacture, and marketing of both drugs and
medical devices, including the Company's iontophoretic drug delivery systems,
are subject to extensive regulation by the FDA in the United States and by
comparable authorities in other foreign countries. These national agencies and
other federal, state and local entities regulate, among other things, research
and development activities and the testing, manufacture, safety, effectiveness,
labeling, storage, record keeping, approval, advertising, promotion and
reporting requirements related to product injury of the Company's products. The
regulations applicable to the Company's products may change as the presently
limited number of approved iontophoretic drug delivery products increases and
regulators acquire additional experience in this area. The FDA has broad
authority to enforce the medical devices and drug regulations and laws, and
noncompliance can result in a variety of regulatory responses ranging from
warning letters and mandatory product recalls to civil or criminal actions and
penalties. See "Risk Factors -- Uncertainty of Government Regulations."
 
                                       48
<PAGE>   50
 
     The Company's iontophoretic drug delivery products involve a medical device
component, thereby subjecting such products to compliance with the FDA's
regulations governing medical devices. Where such medical devices are labeled
for use with a specific pharmaceutical product for a specific therapeutic
indication, they are subject to the FDA's regulations governing both medical
devices and pharmaceutical products. The Company believes that most, if not all,
of its future iontophoretic drug delivery systems will involve a pharmaceutical
component or specific labeling for use with a pharmaceutical product.
 
     Products regulated as medical devices may not be commercially distributed
in the United States unless they have been cleared or approved by the FDA, or
unless they are otherwise exempted from the FDA's regulations. Currently, there
are two methods for obtaining FDA clearance or approval of medical devices.
Devices deemed to pose less risk are placed in class I (general controls) or
class II (general and special controls) and qualify for 510(k) notification, a
procedure under sec. 510(k) of the Federal Food, Drug, and Cosmetic Act (the
"FDC Act"). In order for a device to qualify under the sec. 510(k) notification
procedure, the manufacturer must, among other things, establish that the product
to be marketed is substantially equivalent in intended use and safety and
effectiveness to another legally marketed class I or class II device or to a
"preamendment" class III device (as defined below) for which FDA has not called
for PMAs. In such cases, marketing of the product may commence when the FDA
issues a letter finding that there is a substantial equivalence to the legally
marketed device. The FDA may require, in connection with a 510(k) notification,
the manufacturer to provide the FDA with test results from animal studies and/or
human clinical trials. The Company believes that it typically takes between four
and 12 months to obtain a 510(k) clearance, but it can take longer.
 
     A 510(k) clearance is also required when the manufacturer makes changes or
modifications to a cleared device that could significantly affect safety or
effectiveness, or where there is a major change or modification in the intended
use of a cleared device. In such cases, the manufacturer is the party which
initially determines if the change or modification is of a kind or nature that
would necessitate a new 510(k) notification. The FDA's regulations provide only
limited guidance in making such determinations. The FDA has cleared the
Company's electrical dose controller and electrode kits for marketing under a
510(k) clearance. Since obtaining its 510(k) clearances, the Company has made
modifications to its products. Based on the checklist developed by the FDA to
assist manufacturers in determining whether they are required to obtain a 510(k)
clearance for a modified device, the Company has determined that a new 510(k)
submission was not required in connection with the commercial introduction of
such products. However, there can be no assurance that the FDA will not require
the Company to obtain additional 510(k) clearances with respect to those
products. If the FDA requires the Company to submit a new 510(k) notice for any
device modification, the Company may be prohibited from marketing the modified
device until the 510(k) notice is cleared by the FDA.
 
     A medical device that does not qualify for the 510(k) clearance is placed
in class III, which is reserved for devices deemed by the FDA to pose the
greatest risk (e.g., life-sustaining, life supporting or implantable devices, or
devices that are not substantially equivalent to a legally marketed class I or
II device). The manufacturer of such a device must file a PMA application under
sec. 515 of the Drug Act. A PMA application generally requires a much more
complex submission than a 510(k) notification and typically requires a showing
that the device is safe and effective based on extensive and costly preclinical
and clinical testing, as well as information about the device and its components
regarding, among other things, manufacturing, labeling and promotion. Upon
submission, the FDA determines if the PMA application is sufficiently complete
to permit substantive review and, if so, the application is accepted for filing.
The FDA then commences an in-depth review of the PMA application, which the
Company believes can last from one to three years, or even longer. Even after
approval of a PMA, a new PMA or PMA supplement is required in the event of a
modification to the device, its labeling or its manufacturing process.
 
     A preamendment class III device is one that was on the market before May
28, 1976. A device that is substantially equivalent to a preamendment class III
device can be brought to market through the 510(k) process until the FDA either
calls for the submission of PMA applications or downclassifies the device to
class I or II. Manufacturers of preamendment class III devices that the FDA
retains in class III must submit PMA applications 90 days after the publication
of a final regulation calling for PMAs. In such event, a PMA must be submitted
even if the device has already received 510(k) premarket clearance. On the other
hand, if
 
                                       49
<PAGE>   51
 
the FDA downclassifies a preamendment class III device to class I or II, a PMA
application is not required and such devices may continue to be marketed through
the 510(k) process.
 
     An even more lengthy and complex regulatory framework applies to the
labeling and marketing of specific drugs for use with an iontophoresis device.
The activities required before a pharmaceutical product may be marketed in the
United States primarily begin with preclinical testing. Preclinical tests
include extensive laboratory evaluation of product chemistry and other end
points and animal studies to assess the potential safety and efficacy of the
product as formulated. Almost all preclinical studies pertinent to drug approval
are regulated by the FDA under a series of regulations called the Good
Laboratory Practice (GLP) regulations. Violations of these regulations can, in
some cases, lead to invalidation of the studies, requiring such studies to be
replicated.
 
     If the drug is subject to full NDA requirements, FDA approval process
entails (i) conducting preclinical laboratory and animal testing to enable FDA
authorization of an IND application, (ii) initial IND clinical studies to define
safety and dose parameters, (iii) well controlled IND clinical trials to
demonstrate product safety and efficacy, and (iv) submission to the FDA of an
NDA. Preclinical studies involve laboratory evaluation of product
characteristics and animal studies to assess the efficacy and safety of the
drug. Human clinical trials are typically conducted in three sequential phases.
Phase I trials normally consist of testing the product in a small number of
healthy volunteers for safety and pharmacokinetic parameters using single and
multiple dosing regimens. In Phase II trials, the manufacturer evaluates safety,
initial efficacy, and dose ranging of the product for specific indications in a
somewhat larger patient population. Phase III trials typically involve expanded
testing for safety and clinical efficacy in a broad patient population at
multiple clinical testing centers. The manufacturer must also submit a clinical
plan, or "protocol," accompanied by the approval of the institution
participating in the trials, to the FDA prior to commencing each clinical trial
and must obtain the informed consent of subjects in the clinical trial. The FDA
may order the temporary or permanent discontinuation of clinical trials at any
time. All the results of the preclinical and clinical studies on a product are
then submitted to the FDA in the form of an NDA for review. In responding to an
NDA, the FDA may grant marketing approval, require additional testing and/or
information, or deny the application altogether. The process of obtaining FDA
approval for a new product through the IND/NDA process may take several years
and typically involves the expenditure of substantial resources.
 
     The Company may be subject to certain user fees that the FDA is authorized
to collect under the Food and Drug Modernization Act of 1997, which reauthorized
the user fees established in the Prescription Drug User Fees Act of 1992 for
certain drugs.
 
     Because of the known safety and efficacy profile of Dexamethasone and other
approved drugs for which the Company may seek NDA approval for iontophoretic
delivery, the clinical trials and other studies may not be as lengthy or
extensive as would be required for unapproved new drugs that are subject to full
NDA requirements. This strategy, however, depends upon the Company's ability to
obtain a contractual right to reference in the Company's NDA application of the
safety and efficacy data for such drugs in approved NDAs held by other
companies. The Company has obtained a right to reference safety and efficacy
data for Dexamethasone. There can be no assurance that the Company will be able
to obtain a right of reference for all unapproved drugs that may be used for
iontophoretic delivery. The Company's failure to obtain a right of reference to
safety and efficacy data for any drug for which the Company would like to obtain
approval for iontophoretic delivery could have a material adverse effect on the
Company's business, financial condition and results of operations.
 
     The regulatory status of iontophoresis devices is also complex. The FDA has
classified them as class II devices eligible for marketing through 510(k)
premarket clearance when intended for use with a drug whose labeling bears
adequate directions for the device's use with that drug. However, if an
iontophoresis device is intended for use with a drug that is not labeled for use
with the device, the FDA considers the iontophoresis device to be a preamendment
class III device. This status means that the device at present can be marketed
through a 510(k) clearance, but it remains subject to a call for PMAs.
 
     In an April 1994 document setting forth the FDA's strategy for addressing
preamendment class III devices, the FDA indicated that preamendment class III
iontophoresis devices were among fifteen "high
 
                                       50
<PAGE>   52
 
priority" devices that presented an unreasonably high risk to public health
because significant issues of safety and/or effectiveness were not being
resolved or, to the agency's knowledge, had little probability of being
resolved. The FDA indicated that these devices were not considered candidates
for downclassification and were very likely to be required to be subject to
PMAs. This process would involve two steps. First, the FDA would publish a
proposed regulation to require PMAs for iontophoresis devices having
preamendment class III status. After a comment period, FDA would then publish a
final regulation imposing the requirement. The FDA's strategy document stated
the agency's intent to publish a proposed regulation requiring PMAs for
preamendment class III iontophoresis devices in 1996. The agency, to date, has
not published such a regulation.
 
     The Company's Phoresor received 510(k) clearance in 1990 as a preamendment
class III device labeled for use with ions of soluble salts or other drugs. In
1995, the FDA approved an NDA for Iontocaine to be used as a local anesthetic
and delivered iontophoretically by the Phoresor, which effectively moved the
Phoresor into class II for this intended use. Unlike Iontocaine, Dexamethasone
does not have an NDA approval allowing it to be labeled for iontophoretic
delivery. Thus, the Company's Phoresor is a preamendment class III device when
used with Dexamethasone (or any drug other than Iontocaine). No assurance can be
given that the Company will ever obtain an approved NDA for the iontophoretic
delivery of Dexamethasone. The Company's failure to obtain FDA approval of an
NDA for Dexamethasone could have a material adverse effect on the Company's
business financial condition and results of operations.
 
     If the FDA calls for PMAs for preamendment class III iontophoresis devices,
the Company would be required to have a PMA accepted for filing by the FDA
within 90 days after the date of the final regulation calling for PMAs. There
can be no assurance that the Company would be able to complete necessary
clinical studies and otherwise prepare and file a PMA within the prescribed time
period, or that any data and information submitted in a PMA would be adequate to
support approval. The Company's failure to submit a PMA and have it accepted for
filing by the FDA within the required timeframe could result in the Company
being required to cease commercial distribution of the Phoresor for use with
Dexamethasone. Upon timely filing of a PMA, the Company believes (based on FDA's
announced position as to certain other preamendment class III medical devices)
that the FDA would permit continued commercial distribution of the Phoresor for
use with Dexamethasone during the time necessary to review the PMA. There can be
no assurance, however, that the FDA would permit such continued commercial
distribution pending review of a PMA for the device, nor can any assurance be
given that the FDA would approve a PMA filed by the Company. The FDA also could
condition PMA approval upon approval of an NDA permitting Dexamethasone to be
labeled for use with the Phoresor. If the Company were required for any length
of time to cease commercial distribution of the Phoresis System for use with
Dexamethasone, the Company's business, financial condition and results of
operations would be materially and adversely affected pending approval of a PMA
or NDA.
 
     The FDA also regulates the Company's quality control and manufacturing
procedures by requiring the Company and its contract manufacturers to
demonstrate current GMP compliance, including compliance with the Quality System
Regulation (for devices) and the current GMP regulations (for drugs). The FDA's
GMPs require, among other things, that (i) the manufacturing process be
regulated and controlled by the use of written procedures, and (ii) the ability
to produce products which meet the manufacturer's specifications be validated by
extensive and detailed testing at various steps of the manufacturing process.
These regulations also require investigation of any deficiencies in the
manufacturing process, the products produced, or record keeping. The FDA
monitors compliance with these requirements by requiring manufacturers to
register their manufacturing facilities with the FDA and by conducting periodic
FDA inspections of those facilities. If an FDA inspector observes conditions
that might be in violation of GMP requirements, the manufacturer is generally
required to correct those conditions or explain them satisfactorily. If a
manufacturer fails to adhere to GMP requirements, the devices manufactured by
the manufacturer could be considered to be manufactured in violation of the FDC
Act and the manufacturer could be subject to FDA enforcement action that could
include fines, plant closure, or a recall of the Company's product.
 
     Agencies similar to the FDA regulate medical devices and pharmaceutical
products in most developed foreign countries, whereas some other countries allow
unregulated marketing of such devices and products.
 
                                       51
<PAGE>   53
 
The Company will be required to meet the regulations of any foreign country
where it markets its products. There can be no assurance any of the Company's
future products will receive FDA clearance or similar clearance in foreign
countries. It is also possible that regulations governing the manufacture and
sale of the Company's products could change in the future. The Company cannot
predict the impact of any such changes on its business. See "Risk
Factors -- Government Regulation."
 
     Various aspects of the Company's business and operations are also regulated
by a number of other governmental agencies including the Drug Enforcement
Agency, U.S. Department of Agriculture, the Environmental Protection Agency, the
Occupational Safety and Health Administration as well as by other federal, state
and local authorities. In addition, international sales are regulated by
numerous foreign authorities. Unanticipated changes in existing regulatory
requirements, failure of the Company to comply with such requirements or
adoption of new requirements could have a material adverse effect on the
Company. There can be no assurance the Company will not be required to incur
significant costs to comply with such laws and regulations in the future or that
such laws or regulations will not have a material adverse effect upon the
Company's business, financial condition and results of operations.
 
COMPETITION
 
     The drug delivery, pharmaceutical and biotechnology industries are highly
competitive and rapidly evolving, with significant developments expected to
continue at a rapid pace. The Company's success will depend upon maintaining a
competitive position and developing products and technologies for efficient and
cost effective drug delivery. The Company's products will compete with other
formulations of drugs and with other drug delivery systems, including other
iontophoretic delivery systems. The Company believes its products will compete
on the basis of quality, efficacy, cost, convenience, safety and patient
compliance, but there can be no assurance any of the Company's products will
have advantages significant enough to cause medical professionals to adopt their
use. New drugs or further developments in alternative drug delivery methods may
provide greater therapeutic benefits for a specific drug or indication, or may
offer comparable performance at lower cost than those offered by the Company's
iontophoretic systems.
 
     The Company is aware of many other competitors in the general field of drug
delivery, including competitors developing injectable or implantable drug
delivery systems, oral drug delivery technologies, passive transdermal systems,
oral transmucosal systems and intranasal and inhalation systems. The Company is
also aware of other companies that have developed or are currently developing
iontophoretic and other electrotransport drug delivery systems. There can be no
assurance that developments by these parties or others will not render the
Company's products or technologies uncompetitive or obsolete. Many of the
Company's existing or potential competitors have substantially greater research
and development capabilities, experience, manufacturing, marketing, financial,
and managerial resources than the Company. Accordingly, the Company's
competitors may succeed in developing competing technologies, obtaining FDA
approval or gaining market share for products more rapidly than the Company, any
of which could have a material adverse effect on the Company's business,
financial condition and results of operations.
 
     Both Alza and Empi, Inc. ("Empi") are engaged in the development and/or
marketing of iontophoretic devices. Alza is undertaking the development of
iontophoretic drug delivery systems, but does not currently market any
iontophoretic products. Empi is the Company's primary competitor in the
treatment of acute local inflammation in the physical therapy market and, the
Company estimates, controls a majority of the retail iontophoresis market for
that indication.
 
     Currently, no other company markets an iontophoretic system for the
inducement of local anesthesia. The Company's iontophoretic system for
delivering Iontocaine for the inducement of local dermal anesthesia will
therefore primarily compete with traditional methods of delivering local dermal
anesthetics by needle injection or will be used in circumstances where either no
anesthesia is used, due to the pain associated with the needle injection
(including needle injections themselves), or where topical anesthetic creams are
used. The most effective and widely used topical anesthetic cream, EMLA, is
manufactured and sold by Astra Corporation, a large Swedish pharmaceutical
company. There can be no assurance that the Company can effectively compete with
these products or any other drug delivery systems. See "Risk

of Market Acceptance and Limited Market Penetration" and "Risk
Factors -- Intense Competition and Rapid Technological Change."
 
FACILITIES
 
     The Company maintains leased administrative, manufacturing and research
office space at two facilities. The Company's principal executive offices and
manufacturing facility, which consists of approximately 18,000 square feet of
useable space, are located at 3385 West 1820 South in Salt Lake City, Utah. Its
research facility, which consists of approximately 8,000 square feet of useable
space, is located at 1290 West 2320 South in Salt Lake City, Utah. These
facilities are leased to the Company until December 31, 1999 and December 31,
1997, respectively. The Company is currently negotiating an extension of the
lease on its research and development facilities. The Company believes its
existing facilities are adequate and suitable for its present needs and that
additional space will be available as needed.
 
EMPLOYEES
 
     The Company has assembled a team of medical-products managers and
scientists with considerable experience in iontophoresis, encompassing all of
the key disciplines which the Company believes are necessary to further the
development and implementation of the Company's business.
 
     As of September 1, 1997, the Company had 73 full-time employees, 6 of whom
hold doctorate degrees. Six others hold advanced business or technical degrees.
Of the Company's 73 full-time employees on September 1, 1997, 14 were engaged in
research and development, 35 in manufacturing and quality control, and 24 in
marketing and general administration. The Company's future success depends in
significant part upon the continued service of its key technical and senior
management personnel and its continuing ability to attract and retain highly
qualified technical and managerial personnel. None of the Company's employees is
represented by a labor union. The Company has not experienced any work stoppages
and considers its relations with its employees to be good. See "Risk
Factors -- Retention and Attraction of Key Employees."
 
LEGAL PROCEEDINGS
 
     The Company is not involved in, nor is it aware of, any litigation or
impending litigation.

BOARD OF DIRECTORS AND OTHER INFORMATION
 
     The Company's Articles of Incorporation provide for a classified Board of
Directors consisting of three classes, as nearly equal in number as possible.
The directors in each class serve staggered three year terms. The class three
directors (consisting of Messrs. Wardel and Wood) serve until 1998, the class
two directors (consisting of Mr. Sidwell and Dr. Fara) serve until 1999, and the
class one directors (consisting of Messrs. Weersing and Sember and Dr.
Weinshenker) serve until 2000. At each annual meeting of the shareholders of the
Company, the successors to the class of directors whose term expires at such
meeting will be elected to hold office for a term expiring at the annual meeting
of shareholders held in the third year following the year of their election. The
Company's Articles of Incorporation provide that directors may be removed only
for cause and only by the affirmative vote of the holders of two-thirds of the
Common Shares entitled to vote.
 
BOARD OF DIRECTORS' COMMITTEES
 
     The Board of Directors has established four committees, the Executive
Committee, Audit Committee, Compensation Committee and Special Committee. Each
of these committees is responsible to the full Board of Directors, and its
activities are subject to approval of the Board of Directors. The Executive
Committee is charged with overseeing the operations of the Company, and
generally has all of the authority of the full Board of Directors, between
regularly scheduled meetings of the full Board of Directors. The Executive
Committee is comprised of Mr. Weersing, Dr. Weinshenker and Mr. Wardle. The
Audit Committee reviews the scope and results of the annual audit of the
Company's consolidated financial statements conducted by the
 
                                       56
<PAGE>   58
 
Company's independent accountants, the scope of other services provided by the
Company's independent accountants, proposed changes in the Company's financial
and accounting standards and principles, and the Company's policies and
procedures with respect to its internal accounting, auditing and financial
controls. The Audit Committee also examines and considers other matters relating
to the financial affairs and accounting methods of the Company, including the
selection and retention of the Company's independent accountants. The Audit
Committee is comprised of Mr. Weersing, Dr. Fara and Mr. Sidwell. The
Compensation Committee administers the Company's compensation programs, reviews
and recommends to the Board of Directors compensation arrangements for senior
Company management and directors, and performs such other duties as may from
time to time be determined by the Board of Directors. In addition, the
Compensation Committee is responsible for administering the Company's stock
option plans. The Compensation Committee is comprised of Mr. Weersing, Dr. Fara
and Mr. Wardle. There are no interlocking relationships, as described by the
Securities and Exchange Commission, between the Compensation Committee members.
The Special Committee is charged with overseeing the actions to be taken by the
Company with respect to the Offering, and generally has all of the authority of
the full Board of Directors on issues relating to the Offering. The Special
Committee is comprised of Dr. Weinshenker, Mr. Weersing and Mr. Wood. See
"Employee Benefit Plans."
 
DIRECTOR COMPENSATION
 
     Directors are not paid any cash compensation for attendance at directors'
meetings or for attending or participating on any committee. Directors are
reimbursed, however, for any reasonable out-of-pocket expenses they incur in
connection with attendance at meetings. In addition, all non-employee directors
are eligible to participate in the Company's stock option plans. Upon the
approval of the Board of Directors, certain non-employee directors have been
granted non-qualified options to purchase Common Shares. Dr. Fara and Messrs.
Sidwell and Wood have received options to purchase 6,250, 5,208 and 4,166 Common
Shares, respectively. The option grants vest over a four-year period. All such
options are exercisable at an exercise price equal to the fair market value of
the Common Shares on the date of grant (as adjusted for stock splits and similar

shares subject to any such grants, and the exercise price(s) of the stock
underlying those grants, are determined by the Compensation Committee and
approved by the Board of Directors.

(1) For purposes of determining the values of the options held by the Named
    Executive Officers, the Company has assumed that the Common Shares
    underlying the options had a value of $6.72 per share on June 30, 1997,
    which is the estimated fair market value the Board of Directors attributed
    to the Common Shares in March, 1997, in connection with certain grants of
    options under the Company's stock option plans. The option value is based on
    the difference between the fair market value of the shares on June 30, 1997,
    and the option exercise price per share, multiplied by the number of Common
    Shares subject to the option.
 
LIMITATIONS OF LIABILITY AND INDEMNIFICATION
 
     The Company's Articles of Incorporation limit the personal liability of
directors and officers for monetary damages to the maximum extent permitted by
Utah law. Under Utah law, such limitations include monetary damages for any
action taken or failed to be taken as an officer or director except for (i)
amounts representing a financial benefit to which the person is not entitled,
(ii) liability for intentional infliction of harm on the corporation, or its
shareholders, (iii) unlawful distributions, or (iv) an intentional violation of
criminal law. The Articles of Incorporation also provide that the Company will
indemnify its directors and officers against any damages arising from their
actions as agents of the Company, and that the Company may similarly indemnify
its other employees and agents. The Company is also empowered under its Articles
of Incorporation to enter into indemnification agreements with its directors and
officers.
 
     The Company's Bylaws provide that, to the full extent permitted by the
Company's Articles of Incorporation and the Utah Revised Business Corporation
Act, the Company will indemnify (and advance expenses to) the Company's
officers, directors and employees in connection with any action, suit or
proceeding (civil or criminal) to which those persons are made party by reason
of their being a director, officer or employee.
 
     At present, there is no pending litigation or proceeding involving any
director, officer, employee or agent of the Company where indemnification by the
Company would be required or permitted. The Company is not aware of any
threatened litigation or proceeding which would result in a claim for such
indemnification.

EMPLOYEE BENEFIT PLANS
 
     Stock Option Plans. The Company has adopted and approved two incentive
compensation plans. The Company's 1988 Stock Option Plan (the "Stock Option
Plan") was approved and adopted by the Company's Board of Directors in April
1988 and was approved by its shareholders in November 1988. The Company's 1997
Share Incentive Plan (the "Share Incentive Plan") was approved and adopted by
the Company's Board of Directors in October 1997 and was approved by its
shareholders in November 1997. The Stock Option Plan and Share Incentive Plan
provide for grants to employees, officers, directors and consultants of both
non-qualified stock options and "incentive stock options" (within the meaning of
Section 422 of the Internal Revenue Code of 1986, as amended (the "Code")). The
Share Incentive Plan also provides for the grant of certain other incentive
compensation, including stock awards, stock appreciation rights, dividend
equivalent rights, performance-based awards and cash bonus rights. The purpose
of the Stock Option Plan and Share Incentive Plan is to attract and retain the
best available personnel to the Company and to encourage stock ownership by the
Company's employees, officers, directors and consultants in order to give them a
greater personal stake in the success of the Company.
 
     A total of 520,833 Common Shares were reserved for issuance under the Stock
Option Plan. As of November 1, 1997, options to purchase a total of 135,679
Common Shares had been exercised, options to purchase a total of 339,512 Common
Shares at a weighted average exercise price of $4.80 per share were outstanding,
and 45,642 Common Shares remained available for future option grants or awards.
A total of 312,500 Common Shares were reserved for issuance under the Share
Incentive Plan. The Board of Directors has not granted any options for, or
issued any Common Shares under, the Share Incentive Plan.
 
     The Stock Option Plan is administered by the Compensation Committee, which
determines and designates the recipients of the options, the dates the options
are granted, the number of Common Shares subject to the options, option prices,
vesting terms, fair market value of the Common Shares, duration of the options
and whether any options granted to employees are to be incentive stock options
or non-qualified options.
 
     The exercise price of all options granted under the Stock Option Plan must
be at least 100% of the fair market value of the Common Shares on the grant
date. The term of an option may not exceed ten years from the date of grant.
With respect to any participant who owns shares possessing more than 10% of the
voting power of all classes of shares of the Company, the exercise price of any
option granted must be at least 110% of the fair market value of the Common
Shares on the grant date and the term of such option may not exceed five years.
No incentive options may be granted to a participant which, when aggregated with
all other incentive options granted to that participant, would have an aggregate
fair market value in excess of $100,000 becoming exercisable in any calendar
year.
 
     No option may be transferred by the optionee other than by will or the laws
of descent and distribution. During the lifetime of an optionee, only the
optionee may exercise an option. An option is exercisable on or after each
vesting date in accordance with the terms set forth in the option agreement.
Incentive options are exercisable only during the optionee's employment by the
Company, and for a period of up to 90 days after the termination of the
optionee's employment.
 
     The Share Incentive Plan is also administered by the Compensation
Committee, which in general is responsible for determining the type, amount and
terms of any consideration awarded to a recipient. Under the Share Incentive
Plan, any options granted to a recipient are exercisable in accordance with the
terms of the agreement governing the grant. If the option is an incentive stock
option, those terms must be consistent with the requirements of the Code, as
amended, and applicable regulations, including the requirement that the option
price not be less than the fair market value of the Common Shares on the date of
the grant. If the option is not an incentive stock option, the option price may
be any price determined by the Compensation Committee.
 
     In addition to incentive stock options and non-incentive stock options, the
Compensation Committee may award other types of incentive compensation under the
Share Incentive Plan. Such additional incentive compensation can include stock
awards, stock appreciation rights (which entitle the holder of the right upon
 
                                       59
<PAGE>   61
 
exercise thereof to receive payment from the Company of an amount equal in value
to the excess of the fair market value of the Company's Common Shares on the
date of exercise over the fair market value of the Company's Common Shares on
the date of grant or, if granted in connection with an option, the option price
per share under the option to which the stock appreciation right relates), cash
bonuses, performance-based awards (which are intended to qualify as
performance-based compensation under sec. 162(m) of the Code) and Common Shares
which are subject to a purchase agreement between the Company and the
prospective recipient.
 
     401(k) Plan. In 1990, the Company adopted a deferred compensation plan
under sec. 401(k) of the Code (the "401(k) Plan"). Each full-time employee who
has completed at least one year of service with the Company and has reached age
21 is eligible to make pre-tax elective deferral contributions of up to 20% of
their total compensation per plan year, subject to a specified maximum
contribution as determined by the Internal Revenue Service. The Company matches
the employee's contribution on a formula of $0.25 to the dollar, not to exceed
three percent of the employee's gross annual compensation. The vesting schedule
of the employer match is 33 1/3% per year, over three years. Any potential
forfeitures of the Company's portion of the contribution that do not become
vested are reallocated to the remaining employees in the 401(k) Plan based on
their account balance as a percentage of the whole.

                              CERTAIN TRANSACTIONS
 
     In July 1995, the Company entered into a research and development agreement
with the predecessor to Novartis. The collaboration was formed to evaluate the
potential for development of iontophoretic drug delivery systems for a number of
Novartis compounds for several therapeutic applications. In connection with the
collaboration, Novartis purchased a 20% equity interest in Dermion. Pursuant to
the R&D Agreements, as amended, Novartis is required to pay research costs under
the program and to make milestone payments if Dermion successfully completes
certain objectives. The R&D Agreements may be terminated by either party for any
reason upon six months notice. In addition, the Company granted Novartis a
perpetual, non-exclusive, royalty-bearing license to certain of the Company's
iontophoretic technology, as well as certain rights with respect to future
technology developed or acquired by the Company. In addition, the Company agreed
to certain limitations on its ability to develop products in certain Novartis
fields. Novartis also shares rights to all technology jointly developed pursuant
to the collaboration.
 
     Effective November 1, 1997, the Company, Dermion and Novartis amended the
terms of their relationship by entering into the 1997 Amendments. Under the 1997
Amendments, Novartis exchanged its 20% equity interest in Dermion for 238,541
Common Shares and warrants to acquire 18,750 Common Shares at an exercise price
of $21.60 per share. One-third of Novartis' warrants are currently exercisable.
Another one-third will be exercisable if Novartis commits to provide research
and development funding under the R&D Agreements for 1999. The balance will be
exercisable if Novartis commits to such funding for the year 2000. See
"Business -- Collaborative Relationships and Licenses."
 
     In March 1997, the Company entered into the Elan Agreements, an exclusive,
worldwide license to certain of Elan's iontophoretic drug delivery technology,
including over 250 issued and 47 pending United States and foreign patents, as
well as a significant body of know-how and preclinical and clinical study
results. The Company acquired the Elan technology by issuing Elan two promissory
notes, a $10.0 million note and a $5.0 million note. The Company also issued a
warrant to Elan to acquire 104,166 Common Shares at $21.60 per share and agreed
to pay Elan a royalty on the net revenues derived from sales of all of the
Company's products. The promissory notes each bear interest at the rate of prime
plus 1% (9 1/2% as of June 30, 1997), and the $5.0 million note is secured by
the technology rights the Company acquired in the transaction. Concurrently with
the closing of the Offering, Elan will acquire, directly from the Company in
private placement transactions, approximately 833,333 Common Shares (subject to
adjustment as described below) for approximately $10.2 million (the amounts
outstanding under the $10.0 million note) and approximately $5.1 million of
Common Shares at a price per share equal to the initial public offering price
hereunder. Simultaneously with such purchases, the Company will repay the Elan
Notes, including interest thereon. If the initial public offering price
hereunder is less than $12.00 per share, the number of Common Shares that Elan
will have the right to purchase for the approximately $10.2 million (the amounts
outstanding under the $10.0 million note) will be equal to approximately $10.2
million divided by the initial public offering price hereunder. If, as a result
of Elan's purchase of the Elan Shares, Elan's aggregate interest in the Common
Shares exceeds 19.9% of the outstanding Common Shares, Elan may elect to receive
non-voting preferred shares of the Company to the extent of such excess. Any
such preferred shares would rank pari passu with the Common Shares, be
non-voting and convertible into Common Shares initially on a one-for-one basis.

Related to the Offering."

COMMON SHARES
 
     Subject to preferences that may be applicable to any then outstanding
Preferred Shares, holders of Common Shares are entitled to receive, ratably,
such dividends as may be declared by the Board of Directors out of funds legally
available therefore. In the event of a liquidation, dissolution or winding up of
the Company, holders of the Common Shares are entitled to share ratably in all
assets remaining after the payment of liabilities and the liquidation preference
of any then outstanding Preferred Shares. Holders of Common Shares have no
preemptive rights and no right to convert their Common Shares into any other
securities. There are no redemption or sinking fund provisions applicable to the
Common Shares. All outstanding Common Shares are, and all Common Shares to be
outstanding upon completion of the Offering will be, fully paid and
nonassessable. The holders of Common Shares are entitled to one vote for each
share held of record on all matters submitted to a vote of shareholders. The
Company has not paid, and does not intend to pay, cash dividends on the Common
Shares for the foreseeable future.
 
PREFERRED SHARES
 
     As of November 1, 1997, there were 28,800 Series C Preferred Shares issued
and outstanding. The Series C Preferred Shares are subject to mandatory
conversion, on a share-for-share basis, into Common Shares upon the closing of
an initial public offering and will be converted in connection with the closing
of the Offering.
 
     The Board of Directors will have the authority to issue Preferred Shares in
one or more series and to affix the rights, preferences, privileges and
restrictions thereof, including dividend rights, conversion rights, voting
rights, redemption terms, liquidation preferences and the number of shares
constituting any series, without any further vote or action by the shareholders.
The issuance of Preferred Shares in certain circumstances may have the effect of
delaying or preventing a change in control of the Company. The issuance of
Preferred Shares with voting and conversion rights may adversely affect the
voting power and rights of the holders of Common Shares.
 
WARRANTS
 
     The Company has issued four warrants which, in the aggregate, entitle the
holders thereof to acquire 169,791 Common Shares. On November 1, 1997, the
Company issued Novartis warrants to acquire, through November 1, 2002, 18,750
Common Shares at an exercise price of $21.60 per share. One-third of the
Novartis warrants are currently exercisable. Another one-third of the warrants
are exercisable if Novartis agrees to certain funding commitments under its
agreements with the Company for 1999, and the other one-third of the warrants is
exercisable if Novartis makes such funding commitments for the year 2000. Under
the Elan Agreements, Elan was issued a warrant to acquire, through April 19,
2002, 104,166 Common Shares at an exercise price of $21.60 per share. On
December 1, 1996, the Company issued ACH a warrant to acquire, through December
1, 2003, 44,791 Common Shares at an exercise price of $8.88 per share. On June
25, 1992, the Company issued a warrant to Silicon Valley Bank to acquire,
through June 24, 2002, 2,083 Common Shares at an exercise price of $4.80 per
share.
 
     In connection with the closing of the Offering, the Company has agreed to
issue to the Representatives, warrants to purchase, after the first anniversary
of the date hereof, an aggregate of 170,000 Common Shares at a price per share
equal to (i) 125% of the initial public offering price set forth on the cover
page of this Prospectus after the first anniversary of the date of this
Prospectus or (ii) 150% of the initial public offering price set forth on the
cover page of this Prospectus after the third anniversary of the date of this
Prospectus. The Representatives's Warrants expire on the fifth anniversary of
the date of this Prospectus.
 
ANTI-TAKEOVER EFFECT OF UTAH LAW AND CERTAIN PROVISIONS OF THE ARTICLES OF
INCORPORATION
 
     The Company's Articles of Incorporation require that any action required or
permitted to be taken by shareholders of the Company must be effected at a duly
called annual or special meeting of shareholders. Utah law provides that any
action which may be taken at any annual or special meeting of shareholders may
be taken without a meeting and without prior notice, if one or more consents in
writing, setting forth the action
 
                                       64
<PAGE>   66
 
to be taken, are signed by the holders of outstanding shares having at least the
minimum number of votes that would be necessary to take the action at a meeting
at which all shares entitle to vote on the matter were present and voted. This
provision generally applies to all Utah corporations formed after 1992 and all
Utah corporations formed before 1992 that have amended their articles of
incorporation to provide for actions by consent. The Company is not entitled to
take advantage of that consent provision because it was formed prior to 1992 and
its shareholders have not amended its Articles of Incorporation to allow consent
actions. Special meetings of the shareholders of the Company may be called only
by the Board of Directors, the Chief Executive Officer of the Company or by any
person or persons holding shares representing at least 10% of the outstanding
capital stock. See "Management -- Executive Officers, Directors and Key
Employees."
 
     Utah has adopted legislation which is designed to delay the ultimate
success of a hostile tender offer for shares of a public company until that
tender offer has been approved by a majority of the shareholders. The
legislation applies to all corporations which have not opted out of its
provisions and which have more than 100 shareholders, maintain their principal
place of business or principal office in the State of Utah and where either 10%
or more of the corporation's shareholders reside in Utah or more than 10% of its
outstanding shares are owned by Utah residents. Under the terms of the Company's
Bylaws, the Company has opted out of these provisions.
 
     The Company's Articles of Incorporation provide for the division of the
Board of Directors into three classes, as nearly equal in size as possible, with
staggered three year terms. See "Management." In addition, the Articles of
Incorporation provide that directors may be removed only for cause and only by
an affirmative vote of the holders of two-thirds of the Common Shares entitled
to vote. Further, any vacancy on the Board of Directors, however occurring,
including by reason of an increase in the number of persons comprising the Board
of Directors, may only be filled by vote of a majority of the directors then in
office. These provisions could have the effect of making it more difficult for a
third party to acquire, or of discouraging a third party from acquiring, control
of the Company.
 
REGISTRATION RIGHTS
 
     Pursuant to the Elan Agreements, at any time following the Offering, Elan
has the right, on not more than two occasions and subject to certain
limitations, to require the Company to use its best efforts to register under

acquire upon exercising its warrant. The Elan Agreements also provide that, if
the Company proposes to file a registration statement under the Securities Act
with respect to an offering by the Company. Elan will be entitled to include all
or part of its shares in that registration, subject to the right of the managing
underwriter to exclude shares from registration to the extent their inclusion
would adversely affect the marketing of the shares to be sold. In connection
with the Offering, Elan has agreed not to sell or otherwise dispose of its
shares for a period of 180 days following the Offering. See "Shares Eligible for

the Company is required to notify the holders of the Preferred Investors Shares,
and subject to certain limitations is required to include in such registration

TRANSFER AGENT AND REGISTRAR
 
     American Securities Transfer & Trust, Inc. will be the transfer agent and

                        SHARES ELIGIBLE FOR FUTURE SALE
 
     Upon completion of the Offering, the Company will have outstanding an
aggregate of 6,360,204 Common Shares. In addition, the Company has reserved for
issuance 679,303 shares issuable upon exercise of outstanding options and
warrants, including the Representatives' Warrants. The 1,700,000 Common Shares
offered hereby will be freely transferable without restriction or further
registration under the Securities Act, except for shares which may be acquired
by "affiliates" of the Company as that term is defined in Rule 144 under the
Securities Act. The remaining Common Shares held by existing shareholders are
"restricted securities" as that term is defined in Rule 144. Restricted
securities may be sold in the public market only if they are registered or if
they qualify for exemption from registration under Rules 144 or 701 under the
Securities Act or otherwise. Pursuant to certain "lock-up" agreements, the
Company's directors, officers and certain of its shareholders who collectively
hold an aggregate of 4,560,934 Common Shares, together with the Company, have
agreed, for a period of 180 days following the date of this Prospectus, not to
offer, pledge, sell, contract to sell, grant any option for the sale of, or
otherwise dispose of, directly or indirectly, any Common Shares without the
prior written consent of EVEREN Securities, Inc. Following the lock-up periods,
approximately 1,903,533 Common Shares will be eligible for sale in the public
market without restriction under Rule 144(k) and an additional 79,808 Common
Shares will be eligible for sale subject to certain volume, manner of sale and
other limitations under Rule 144. Of the approximately 76,418 restricted shares
held by existing shareholders of the Company not subject to lock-up agreements,
all such Common Shares will be eligible for immediate sale in the public market
without restriction under Rule 144(k). In addition, holders of stock options or
warrants exercisable for an aggregate of approximately 220,227 Common Shares
have entered into agreements prohibiting sale of the underlying Common Shares
for 180 days following the date of this Prospectus.
 
     In general, under Rule 144 as currently in effect, a person (or persons
whose shares are aggregated), including an affiliate, who has beneficially owned
shares for at least one year is entitled to sell, within any three-month period
commencing 90 days after the date of this prospectus, a number of shares that
does not exceed the greater of (i) 1% of the then outstanding Common Shares
(63,602 shares immediately after the Offering) or (ii) the average weekly
trading volume in the Common Shares during the four calendar weeks preceding
such sale, subject to the filing of a Form 144 with respect to such sale and
certain other limitations and restrictions. In addition, a person who is not
deemed to have been an affiliate of the Company at any time during the 90 days
preceding a sale, and who has beneficially owned the shares proposed to be sold
for at least two years, would be entitled to sell such shares under Rule 144(k)
without regard to the volume, manner of sale and other limitations described
above.
 
     Any employee or consultant to the Company who purchased his or her shares
pursuant to a written compensatory plan or contract is entitled to rely on the
resale provisions of Rule 701, which permit non-affiliates to sell their Rule
701 shares without having to comply with the public information, holding-period,
volume-limitation or notice provisions of Rule 144 and permit affiliates to sell
their Rule 701 shares without having to comply with the Rule 144 holding period
restrictions, in each case commencing 90 days after the date of this Prospectus.
 
     The holders of 4,036,010 Common Shares and warrants to purchase 337,708
Common Shares have certain registration rights. See "Description of Capital
Shares -- Registration Rights."

</TABLE>
 
     The Underwriting Agreement provides that the obligations of the
Underwriters are subject to certain conditions precedent, including the absence
of any material adverse change in the Company's business and the receipt of
certain certificates, opinions and letters from the Company and its counsel and
independent auditors. The nature of the Underwriters' obligation is such that
they are committed to purchase all Common Shares offered hereby if any such
shares are purchased.
 
     The Underwriters propose to offer the Common Shares to the public at the
public offering price set forth on the cover page of this Prospectus, and to
certain dealers at such price less a concession not in excess of $          per
share. The Underwriters may allow to selected dealers and such dealers may
reallow a concession not in excess of $          per share to certain other
dealers. After the public offering of the Common Shares, the offering price and
other selling terms may be changed by the Representatives.
 
     The Company has granted to the Underwriters an option, exerciseable at any
time during the 30-day period after the date of this Prospectus, to purchase up
to an additional 255,000 Common Shares at the initial public offering price set
forth on the cover page of this Prospectus, less underwriting discounts and
commissions. The Underwriters may exercise such option solely for the purpose of
covering over-allotments, if any, in connection with the Offering. To the extent
the option is exercised, each Underwriter will be obligated, subject to certain
conditions, to purchase approximately the same percentage of such additional
shares as the number of Common Shares set forth next to such Underwriter's name
in the preceding table bears to the total number of shares listed in the table.
 
     The Company has agreed to issue to the Representatives warrants to
purchase, after the first anniversary of the date hereof, up to an aggregate of
170,000 Common Shares, at a price equal to (i) 125% of the initial public
offering price set forth on the cover page of this Prospectus after the first
anniversary of the date of this Prospectus or (ii) 150% of the initial public
offering price set forth on the cover page of this Prospectus after the third
anniversary of the date of this Prospectus. Holders of the Representatives'
Warrants have been granted certain demand and piggy-back registration rights
under the Securities Act with respect to the securities issuable upon exercise
of the Representatives' Warrants. See "Description of Shares -- Registration
Rights" and "Shares Eligible For Future Sale." The Representatives' Warrants
expire on the fifth anniversary of the date of this Prospectus.
 
     The Company has also granted the Representatives a nonaccountable expense
allowance of $245,000.
 
     The offering of the Common Shares is made for delivery when, as and if
accepted by the Underwriters and subject to prior sale and to withdrawal,
cancellation or modification of the Offering without notice. The Underwriters
reserve the right to reject an order for the purchase of Common Shares in whole
or in part.
 
     In connection with the Offering, the Underwriters may engage in
transactions that stabilize, maintain or otherwise affect the price of the
Common Shares. Specifically, the Underwriters may over-allot the Offering,
creating a syndicate short position. In addition, the Underwriters may bid for
and purchase Common Shares in the open market to cover syndicate short positions
or to stabilize the price of the Common Shares. Finally, the underwriting
syndicate may reclaim selling concessions from syndicate members in the
Offering, if the syndicate repurchases previously distributed Common Shares in
syndicate covering transactions, in stabilization transactions or otherwise. Any
of these activities may stabilize or maintain the market price of the
 
                                       68
<PAGE>   70
 
Common Shares above independent market levels. The Underwriters are not required
to engage in these activities, and may end any of these activities at any time.
 
     The Representatives have informed the Company that the Underwriters do not
intend to confirm sales to accounts over which they exercise discretionary
authority.
 
     The Company has agreed to indemnify the Underwriters against certain
liabilities, including liabilities under the Securities Act, or to contribute to
payments that the Underwriters may be required to make in respect thereof.
 
     The executive officers, directors and certain employees of the Company and
certain other shareholders have agreed that they will not, without the prior
written consent of EVEREN Securities, Inc., offer, sell or otherwise dispose of
any Common Shares, options or warrants to acquire Common Shares or securities
exchangeable for or convertible into Common Shares for a period of 180 days
after the day of this Prospectus. The Company has agreed that it will not,
without the prior written consent of EVEREN Securities, Inc., offer, sell,
contract, grant any option to purchase or otherwise dispose of any Common
Shares, options or warrants to acquire Common Shares or securities exchangeable
for or convertible into Common Shares for a period of 180 days after the date of
this Prospectus, except for securities issued under its Stock Option Plan or
Share Incentive Plan, the Elan Agreements or upon exercise of currently
outstanding stock options or warrants. See "Shares Eligible for Future Sale."
 
     Prior to the Offering, there has been no public market for the Common
Shares. Consequently, the initial public offering price for the Common Shares
included in the Offering will be determined by negotiations between the Company
and the Representatives. Among the factors considered in determining such price
will be the history of and prospects for the Company's business and the industry
in which it competes, an assessment of the Company's management and the present
state the Company's development, its past and present operations and financial
performance, the prospects for future earnings of the Company, the present state
of the Company's research and development programs, the current state of the
economy in the United States and the current level of economic activity in the
industry in which the Company competes and in related or comparable industries,
and the current prevailing condition in the securities markets, including
current market valuations of publicly traded companies that are comparable to
the Company.
 
                                 LEGAL MATTERS
 
     The validity of the Common Shares offered hereby will be passed upon for
the Company by Parsons Behle & Latimer, Salt Lake City, Utah. Certain legal
matters in connection with the Offering will be passed upon for the Underwriters

                         REPORT OF INDEPENDENT AUDITORS
 
The Board of Directors and Shareholders
IOMED, Inc.
 
We have audited the accompanying consolidated balance sheets of IOMED, Inc. as
of June 30, 1997 and 1996, and the related consolidated statements of
operations, shareholders' equity (deficit), and cash flows for each of the three
years in the period ended June 30, 1997. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.
 
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of IOMED, Inc. at
June 30, 1997 and 1996, and the consolidated results of its operations and its
cash flows for each of the three years in the period ended June 30, 1997, in
conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Description of Business
 
     IOMED, Inc., a Utah corporation (the "Company"), develops, manufactures and
commercializes controllable drug delivery systems using iontophoresis
technology.
 
  Discontinued Operations
 
     On December 31, 1996, the Company sold the assets of its Motion Control
Division, which was engaged in the research, development, manufacture and sale
of advanced myoelectric prosthetic devices. Accordingly, the consolidated
statements of operations for the years ended June 30, 1996 and 1995 have been
restated to present the results of operations of the Motion Control Division as
a discontinued operation (see Note 4).
 
  Principles of Consolidation
 
     The consolidated financial statements include the accounts of the Company
and its 80% owned subsidiary, Dermion, Inc. ("Dermion"). Dermion was formed in
April 1996 to conduct advanced research and development of iontophoretic drug
delivery systems on its own behalf and on behalf of third party clients. The
remaining 20% interest of Dermion is reflected as minority interest in the
accompanying financial statements. All significant intercompany transactions and
accounts have been eliminated.
 
  Cash Equivalents
 
     The Company considers all highly-liquid investments with maturities of
three months or less, when purchased, to be cash equivalents.
 
  Concentrations of Credit Risk
 
     The Company's financial instruments that are exposed to concentrations of
credit risk consist primarily of cash, cash equivalents and trade accounts
receivable. Cash and cash equivalents are held in federally insured financial
institutions or invested in high grade short-term commercial paper issued by
major United States corporations. The Company sells its products primarily to,
and has trade accounts receivable with, independent durable medical equipment
dealers in the United States and abroad. Less than 10% of product sales are to
foreign customers. As a general policy, collateral is not required for accounts
receivable; however, the Company maintains an allowance for losses based upon
expected collections of accounts receivable. Additionally, customers' financial
condition and credit worthiness are regularly evaluated and historical losses
have not been material. During the periods presented, none of the Company's
customers accounted for more than 10% of net product sales. Accordingly, the
Company considers concentrations of credit risk with respect to trade accounts
receivable to be low.
 
  Inventories
 
     Inventories are stated at the lower of cost or market. Cost is determined
using the first-in, first-out method. Inventories consisted of the following
and, at June 30, 1996, included $613,000 in inventory associated with the
Company's discontinued operations:

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
  Equipment and Furniture
 
     Equipment and furniture are stated at cost. Depreciation and amortization
is computed using the straight-line method over estimated useful lives of three
to five years. Leasehold improvements are amortized over the term of the lease
or the useful life of the improvements, whichever is shorter. Equipment and
furniture consisted of the following and, at June 30, 1996, included $50,000 in
equipment net of accumulated depreciation associated with the Company's
discontinued operations:

</TABLE>
 
  Revenue Recognition
 
     Revenues on product sales are generally recognized upon shipment. Contract
research revenue and license fees are recognized as earned.
 
  Patent Development Costs
 
     In connection with its research and development efforts, the Company incurs
certain costs in the preparation, application, filing, maintenance and defense
of patents and trademarks. Where such costs primarily relate to patents and
trademarks covering technologies or products which are under development or in
the early stages of commercialization, the Company expenses such costs as
incurred.
 
  Stock Options
 
     The Company has elected to follow Accounting Principles Board Opinion No.
25, "Accounting for Stock Issued to Employees" (APB 25) and related
Interpretations in accounting for its employee stock options rather than
adopting the alternative fair value accounting provided for under FASB Statement
No. 123, Accounting for Stock-Based Compensation (SFAS 123). Under APB 25,
because the exercise price of the Company's share options equals the market
price of the underlying shares on the date of grant, the Company does not
recognize any compensation expense.
 
  Income Taxes
 
     The Company accounts for income taxes using the asset and liability method.
Under the asset and liability method, deferred tax assets and liabilities are
recognized for the future tax consequences attributable to differences between
the financial statement carrying amounts of existing assets and liabilities and
their respective tax bases, operating loss and tax credit carryforwards.
Deferred tax assets and liabilities are measured using enacted tax rates
expected to apply to taxable income in the years in which those temporary
differences are expected to be recovered or settled. The effect on deferred tax
assets and liabilities of a change in tax rates is recognized in income in the
period that includes the enactment date.
 
  Earnings (Loss) Per Share
 
     The Company's net income (loss) per share is based upon the weighted
average number of common shares outstanding during the periods. Common share
equivalents (stock options, warrants, convertible

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
preferred shares and convertible debt), as determined using the treasury stock
method, have been excluded from the computations in those periods where their
inclusion would have an antidilutive effect. Pursuant to the Securities and
Exchange Commission Staff Accounting Bulletin No. 83, shares and equivalent
shares issued by the Company at prices below the assumed public offering price
during the twelve-month period prior to the proposed offering have been included
in the calculation as if they were outstanding for all periods presented (using
the treasury stock method and using the assumed midpoint of the initial public
offering price range).
 
  New Accounting Pronouncements
 
     In 1997, the FASB issued three new statements, SFAS No. 128-Earnings per
Share, SFAS No. 130-Reporting Comprehensive Income and SFAS No. 131-Disclosures
about Segments of an Enterprise and Related Information. As of June 30, 1997,
these statements were either not effective or not yet adopted by the Company.
The Company believes the new standards will not have a material impact on the
Company's financial statements.
 
  Estimates
 
     Preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities at the date of the
financial statements and the reported amounts of revenue and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Reclassifications
 
     Certain reclassifications have been made to prior year financial statements
to conform to the financial statement presentation included herein.
 
 2. PURCHASE OF IN-PROCESS RESEARCH AND DEVELOPMENT
 
     In March 1997, the Company entered into agreements with Elan Corporation,
plc ("Elan"), an international developer of advanced drug delivery systems, to
obtain an exclusive, worldwide license for the commercial development of certain
of Elan's in-process research and development in the field of iontophoretic drug
delivery, including both issued and pending patents, know-how and clinical data.
Pursuant to the agreements, the Company paid Elan a one time fee of $15,000,000,
issued warrants to purchase up to 500,000 common shares at a price of $21.60 per
share and agreed to pay Elan certain royalties on net revenues derived from
sales of its iontophoretic drug delivery products. Both the number and share
price of the warrants are subject to adjustment for certain corporate
transactions. Payment of the fee was funded by the issuance of two subordinated
convertible notes to Elan in an aggregate principal amount of $15,000,000 (See
Notes 3 and 7).
 
 3. NON-RECURRING CHARGES
 
     The intended clinical applications, as well as alternative future
applications, of the technologies purchased from Elan (see Note 2) are in the
early stages of research, design and clinical development, subject to numerous
technological, regulatory, and commercial risks and, therefore, represent
in-process research and development. Accordingly, during fiscal 1997, the
Company recorded a non-recurring charge of $15,059,000 reflecting the write-off
of the in-process research and development purchased, including the fee and
related transaction costs.
 
     During fiscal 1996, a suit was filed against the Company by a competitor
alleging, among other things, that a recently introduced product of the Company
infringed upon the competitor's trade dress. In February 1996, a federal court
granted the plaintiff's request for a preliminary injunction. Thereupon, the
 
                                       F-9

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
Company entered into a settlement agreement with the plaintiffs. The total costs
incurred in connection with the suit were approximately $430,000, which amount
includes legal fees, court costs and damages paid to the plaintiff, legal fees
incurred by the Company and inventory rework costs. The settlement agreement
will not have any material impact on the Company's ability to continue to
manufacture and sell its products, including the new product which gave rise to
the litigation.
 
 4. DISCONTINUED OPERATIONS
 
     In December 1996, the Company sold the assets of its Motion Control
Division, which was engaged in the research, development, manufacture and sale
of myoelectric prosthetic devices. In addition, the Company granted a worldwide,
exclusive license to certain patent rights covering the products manufactured by
the division to the purchaser. Proceeds from the sale were $1,000,000 and the
Company is entitled to receive royalties on future product sales of the
purchaser. There was no significant gain or loss recognized on the sale.
Included in accounts receivable at June 30, 1996 is $351,000 associated with the
Company's discontinued operations. The results of operations of the Motion
Control Division prior to its sale have been classified as discontinued
operations in the accompanying statements of operations. No interest expense has
been allocated to discontinued operations and both federal and state income
taxes have been calculated and allocated based upon statutory rates. A summary
of the results of discontinued operations is as follows:

 5. INVESTMENTS IN MARKETABLE DEBT SECURITIES
 
     Debt securities are classified as held-to-maturity when the Company has the
intent and ability to hold the security to maturity. Held-to-maturity securities
are stated at amortized cost, adjusted for amortization of premiums and
accretion of discounts to maturity, which approximates quoted fair market
values. Such amortization as well as interest earned is included in interest
income. As of June 30, 1996 and 1997, all investments were classified as
held-to-maturity and consisted of United States corporate securities totaling
$3,757,000 and $4,635,000, respectively, and are included with cash and cash
equivalents.
 
 6. ACCRUED LIABILITIES
 
     Accrued liabilities consisted of the following:

     In 1995, the Company's board of directors approved management's plan to
consolidate the Company's operating facilities. Under the plan, certain office
facilities currently under lease through December 1999 have been left idle.
Accordingly, the Company recorded charges and accrued facilities costs in the
amount of $180,000 and $53,000 in 1995 and 1996, respectively, which represents
the total committed lease obligation for

the idle space, plus estimated maintenance and construction costs. At June 30,
1997, approximately $69,000 of these charges remained in accrued liabilities.
 
 7. SUBORDINATED, CONVERTIBLE DEBT
 
     In connection with the purchase of in-process research and development from
Elan (see Note 2), the Company issued two promissory notes to Elan, the A Note
and the B Note, in the amount of $10,000,000 and $5,000,000, respectively. Both
notes are subordinated to any existing or future indebtedness incurred to
finance working capital or the purchase of fixed assets in the normal course of
business. The carrying value of these notes approximates fair market value since
interest rates are based upon current market rates.
 
     The A Note accrues interest at prime plus one percent (9.5% at June 30,
1997), payable at maturity. Upon the completion of an initial registered public
offering of common shares or in any event on April 1, 1999, the note, together
with all accrued interest thereon, will be exchanged for common shares of the
Company. If the triggering event is an initial registered public offering, the
Company will issue 833,333 common shares, as adjusted for certain corporate
transactions, in exchange for the note. If an initial public offering is not
previously consummated, then on April 1, 1999, in exchange for the indebtedness
under the A Note, the Company will issue shares at an exchange price of $12.00
per share, which exchange price is subject to adjustment under certain
conditions.
 
     The B Note accrues interest at prime plus one percent (9.5% at June 30,
1997). The B Note plus any accrued and unpaid interest thereon will become due
and payable immediately upon the completion of an initial registered public
offering of common shares. If not pre-paid pursuant to an initial registered
public offering or otherwise, the B Note, becomes due and payable in five equal
installments of principal of $1,000,000 on each of the fifth, sixth, seventh,
eighth and ninth anniversaries of the note, together, in each case with any
accrued and unpaid interest thereon.
 
     In June 1993, the Company entered into a research and development agreement
with Laboratoires Fournier, a French pharmaceutical company ("Fournier") to
collaborate in the joint development and commercialization of certain drug
delivery systems. In connection with this transaction, in July 1993, the Company
borrowed $3,000,000 ($2,923,000, net of debt issuance costs) from Fournier
pursuant to a subordinated, convertible note. In March 1996, the companies
reached a mutual agreement to terminate their collaborative development efforts.
Among other things, the agreement provided for the conversion of the $3,000,000
subordinated, convertible note, at a conversion rate of $8.88 per share, into
337,838 common shares.
 
 8. COMMITMENTS
 
     The Company leases space and certain equipment under noncancellable
operating lease agreements that expire at various dates through December 1999.
Rental expense for such leases was $225,000, $227,000 and $218,000 for the years
ended June 30, 1995, 1996 and 1997, respectively. It is generally expected that,
in the normal course of business, operating leases that expire will be renewed
or replaced by other leases with similar terms. Future minimum lease payments
under noncancellable operating leases (with initial or remaining lease terms in
excess of one year) at June 30, 1997 were $86,000.
 
 9. ROYALTY AGREEMENTS
 
     The Company is the licensee under a royalty agreement with the University
of Utah Research Foundation. This agreement provides for the payment of
royalties to the licensor based upon net sales of the products under royalty
until the year 2006. Royalty expense in each of the three years in the period
ended June 30, 1997 was not material.

10. REDEEMABLE, CONVERTIBLE PREFERRED SHARES
 
     In connection with a reorganization of the Company in fiscal 1988, the
Company issued 878,254 shares of $.001 par value redeemable convertible
preferred shares in three series; Series A, Series B and Series C. Pursuant to
the terms of such preferred shares, the Series A shares were redeemed in equal
installments beginning in July 1992 through July 1996 at a redemption price of
$25.00 per share and the Series B shares (828,254 shares with a carrying value
of $1,500,000) were converted prior to July 15, 1996 into common shares on a
share for share basis at the equivalent of $1.811 per share.
 
     The Series C preferred shares outstanding as of June 30, 1997 are comprised
of 36,000 shares with an aggregate redemption value of $900,000. The Series C
preferred shares are redeemable at $25.00 per share in five equal annual
installments beginning in July 1997. Unless converted to common shares,
mandatory redemption requirements on the Series C preferred shares are $180,000
annually from 1998 through 2002. The Company may redeem all or part of the
preferred shares to the extent of its unreserved and unrestricted retained
earnings at any time prior to the required redemption dates.
 
     Prior to redemption, each share of the Series A, B and C preferred shares
either are, or were, as applicable, convertible on a share for share basis, at
the option of the holder, into common shares. The conversion ratio is subject to
adjustment based on the issue price of additional shares, options, or rights to
common shares issued. Each outstanding preferred share will automatically
convert to one common share upon the sale of common shares of the Company
pursuant to a registration statement under the Securities Act of 1933, the
public offering price of which is not less than $5.4331 per share and which
results in gross proceeds to the Company of at least $5,000,000.
 
     Each share of the Series A, B and C preferred shares has a voting right
equal to one vote for each common share into which the preferred share could be
converted as outlined above. The holders of the preferred shares have voting
rights and powers equal to those of the holders of common shares and vote with
the holders of common shares and not as a separate class. Under no circumstances
are the holders of any series of preferred shares entitled to vote separately on
any matter.
 
     Dividends are non-cumulative and are to be paid on the preferred shares
only as authorized by the Board of Directors. In the event of liquidation of the
Company, each outstanding preferred share converts into one common share. No
dividend (other than a dividend payable solely in common shares) may be declared
or paid on common shares unless an equal or greater dividend per share has first
been declared and paid on each preferred share. Each preferred share, regardless
of its series, must be paid the same dividend per share. No dividends have been
declared or paid to date.
 
11. RESEARCH & DEVELOPMENT
 
     In July 1995, the Company entered into an interim research and development
agreement with Ciba-Geigy Corporation ("Ciba"), an affiliate of a Swiss
pharmaceutical company, to evaluate the feasibility of delivering certain Ciba
compounds using the Company's iontophoretic drug delivery technologies. In March
1996, this interim agreement was superseded by a long-term research and
development agreement with Ciba. In conjunction with the research and
development agreement, the Company formed Dermion, a wholly-owned subsidiary
established to conduct advanced iontophoretic drug delivery systems development.
The Company contributed cash, fixed assets and non-exclusive licenses to certain
technology, valued at a historical cost of approximately $1,300,000 to Dermion,
in exchange for common shares. Concurrently, Ciba acquired a 20% equity interest
in Dermion for $1,000,000 in cash. Pursuant to a separate shareholder's
agreement, Ciba is entitled to a premium of up to $1,250,000 in the event of a
change in control of Dermion.
 
     Ciba-Geigy Corporation and Sandoz Corporation merged and, as a result,
formed Novartis Pharmaceuticals Corporation.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
     Currently, the term of the agreement extends through December 31, 1998. The
agreement automatically renews for additional one year terms, unless terminated,
by either party, with written notice six months prior to any anniversary date.
During the term of the research and development agreement, Novartis is obligated
to provide Dermion with research funding for the development of proprietary
iontophoretic drug delivery systems designed to deliver Novartis compounds.
Also, during the term of the agreement, Novartis has certain rights to the
Company's technologies for certain specific therapeutic indications using
Novartis proprietary drugs or specified generic compounds. The agreement further
provides that Dermion will be entitled to milestone payments upon the
achievement of certain performance targets and to future royalties on Novartis'
sales of products developed pursuant to the research. Dermion is currently
devoting the majority of its research and development capabilities to the
development of these systems for Novartis. Research funding payments and license
fees paid pursuant to the agreement with Novartis totaled $2,409,000 and
$1,750,000, respectively, in fiscal years ended June 30, 1996 and 1997. As of
June 30, 1997, the Company had a receivable, in the amount of $301,000, due from
Novartis, for research services rendered, which is included in accounts
receivable in the accompanying balance sheet.
 
12. EMPLOYEE BENEFIT PLAN
 
     The Company has established a 401(k) savings plan for its full-time
employees. The Company makes a matching contribution based on a percentage of
the contributions of participating employees. The Company contributed
approximately $24,000 during each of the years ended June 30, 1995 and 1996 and
approximately $19,000 during fiscal 1997.
 
13. INCOME TAXES
 
     Deferred taxes result from differences in the carrying value of various
assets and liabilities between income tax reporting and financial reporting
purposes. These differences arise from differing depreciation methods, and other
reserves that are deductible in different periods for tax and financial
reporting purposes.
 
     The approximate tax effect of temporary differences, net operating loss
carryforwards and tax credit carryforwards as of June 30, 1997 and 1996 is as
follows:

     As of June 30, 1997, the Company had approximately $4,147,000 in federal
and state net operating loss carryforwards, and $577,000 in federal tax credit
carryforwards, that expire from 2001 through 2012. Utilization of the Company's
net operating loss and credit carryforwards is limited to the future taxable
income of the Company. Under the "change of ownership" provisions of the
Internal Revenue Code, utilization of these net operating loss and credit
carryforwards may be subject to substantial annual limitation.
 
14. STOCK OPTIONS AND WARRANTS
 
     The Company has an Employee Stock Option Plan (the Plan) for which 520,833
common shares have been reserved. The Plan allows grants of incentive options
and nonqualified options to purchase common shares at a price that is not less
than the fair market value on the date of grant. The option price and dates the
options become exercisable and expire are determined by the Board of Directors
on an option-by-option basis.
 
     Pro forma information regarding net income and earnings per share has been
determined as if the Company had accounted for its employee stock options under
the fair value method. The fair value of these options was estimated at the date
of grant using a Minimum Value option pricing model with the following weighted
average assumptions for fiscal years ended June 30, 1996 and 1997: risk-free
interest rate of approximately 6.4% and 6.3%; dividend yield of 0%; and a
weighted-average expected life of the option of 6 years.
 
     For purposes of pro forma disclosures, the estimated fair value of the
options is amortized over the options' vesting period. Because the effect of
SFAS No. 123-Accounting for Stock Based Compensation is prospective, the initial
impact on pro forma net income (loss) may not be representative of compensation
expense in future years. The effect on the Company's pro forma results for each
of the fiscal years ended June 30, 1996 and 1997 was not material (less than
$0.05 per share).

 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Description of Business
 
     IOMED, Inc., a Utah Corporation (the "Company"), develops, manufactures and
commercializes controllable drug delivery systems using proprietary
iontophoretic technology. Iontophoresis is a method of enhancing and controlling
the transport of drugs through the skin utilizing a low level electrical
current.
 
  Discontinued Operations
 
     On December 31, 1996, the Company sold the assets of its Motion Control
Division, which was engaged in the research, development, manufacture and sale
of advanced myoelectric prosthetic devices. Accordingly, the consolidated
statement of operations for the three months ended September 30, 1996 presents
the results of operations of the Motion Control Division as a discontinued
operation. There were no remaining assets or liabilities related to discontinued
operations reflected in the financial statements as of September 30, 1997 or
June 30, 1997.
 
  Principles of Consolidation
 
     The consolidated financial statements include the accounts of the Company
and its 80% owned subsidiary Dermion, Inc. ("Dermion.") Dermion was formed in
April 1996 to conduct advanced research and development of iontophoretic systems
on its own behalf and on behalf of third party clients. All significant
intercompany transactions and accounts have been eliminated.
 
  Basis of Presentation
 
     In the opinion of management, the accompanying condensed consolidated
financial statements contain all normal recurring adjustments necessary to
present fairly the financial position of the Company as of September 30, 1997
and the results of its operations and cash flows for the three month periods
ended September 30, 1997 and 1996. The operating results for the interim periods
are not necessarily indicative of the results for a full year. These statements
should be read in conjunction with the Company's audited consolidated financial
statements for the year ended June 30, 1997, included elsewhere in this
prospectus.
 
  Earnings (Loss) Per Share
 
     The Company's net income (loss) per share is based upon the weighted
average number of common shares outstanding during the periods. Common stock
equivalents (stock options, warrants, convertible preferred stock and
convertible debt), as determined using the treasury stock method, have been
included in such computations for the three month period ended September 30,
1996 and, except as noted below, have been excluded from the computations in the
three month period ended September 30, 1997 where their inclusion would have an
antidilutive effect.
 
     Pursuant to the Securities and Exchange Commission Staff Accounting
Bulletin No. 83, shares and equivalent shares issued by the Company at prices
below the assumed public offering price during the twelve-month period
immediately prior to the proposed public offering have been included in the
calculation of earnings per share (using the treasury stock method and using the
midpoint of the initial public offering range), as if they had been outstanding
for all periods presented, including periods in which such securities have an
antidilutive effect. Additional SAB No. 83 shares included in the computation of
per share amounts were 15,130 and 52,332 for the three month periods ended
September 30, 1997 and 1996, respectively.

  3. DISCONTINUED OPERATIONS
 
     In December 1996, the Company sold the assets of its Motion Control
Division which was engaged in the research, development, manufacture and sale of
myoelectric prosthetic devices. In addition, the Company granted a worldwide,
exclusive license to certain patent rights covering the products manufactured by
the division to the purchaser. Proceeds from the sale were $1,000,000 and the
Company is entitled to receive royalties on future product sales of the
purchaser. There was no significant gain or loss recognized on the sale. The
results of operations of the Motion Control Division prior to its sale have been
classified as discontinued operations in the accompanying statements of
operations. No interest expense has been allocated to discontinued operations
and both federal and state income taxes have been calculated and allocated based
upon statutory rates. A summary of the results of discontinued operations is as
follows:

 4. SUBSEQUENT EVENTS
 
  Initial Public Offering
 
     On October 3, 1997, the Company filed a registration statement on Form S-1
with the Securities and Exchange Commission pursuant to which the Company
intends to consummate an initial public offering of newly issued common shares.
 
  Reverse Stock Split
 
     On November 7, 1997, pursuant to a vote of the shareholders, the Company
effected a one for 4.8 reverse share split for each common and preferred share
then outstanding and amended and restated its Articles of Incorporation and
Corporate Bylaws. Among other things, these amendments changed the par value of
the Company's common shares from $0.001 per share to no par value common shares;
increased the number of authorized common shares from 40,000,000 shares to
100,000,000 shares; and increased the number of authorized preferred shares from
4,215,618 shares to 10,000,000 shares. For comparative purposes, all share
amounts in the accompanying financial statements and related footnotes have been
retroactively restated to reflect the effects of the reverse stock split and the
increases in the authorized shares of the Company's common and preferred shares.

  Novartis Exchange Agreement
 
     Effective November 1, 1997, the Company entered into an Exchange Agreement
with Novartis Pharmaceuticals Corporation. Among other things, the Exchange
Agreement provided for the exchange of Novartis' 20% minority interest in
Dermion, the Company's research and development subsidiary, for 238,541 common
shares of the Company and warrants to purchase, under certain conditions,
through November 1, 2002, an additional 18,750 common shares at a price equal to
$21.60 per share, making Dermion a wholly owned subsidiary of Iomed, Inc. In
addition, the Company and Novartis amended their research and development
agreement to, among other things, expand Iomed's rights to conduct research and
development in areas other than in the areas of acute local inflamation and
local dermal anesthesia.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     The Company's Articles of Incorporation limit the personal liability of
directors and officers for monetary damages to the maximum extent permitted by
Utah law. Under Utah law, such limitations include monetary damages for any
action taken or failed to be taken as an officer or director except for (i)
amounts representing a financial benefit to which the person is not entitled,
(ii) liability for intentional infliction of harm on the Corporation or its
shareholders, (iii) unlawful distributions, or (iv) an intentional violation of
criminal law. The Articles of Incorporation also provide that the Company will
indemnify its directors and officers against any damages arising from their
actions as agents of the Company, and that the Company may similarly indemnify
its other employees and agents. The Company is also empowered under its Articles
of Incorporation to enter into indemnification agreements with its directors and
officers.
 
     The Company's Bylaws provide that, to the full extent permitted by the
Company's Articles of Incorporation and the Utah Revised Business Corporation
Act, the Company will indemnify (and advance expenses to) the Company's
officers, directors and employees in connection with any action, suit or
proceeding (civil or criminal) to which those persons are made party by reason
of their being a director, officer or employee). Any such indemnification will
be in addition to the advancement of expenses.
 
     The terms of the Company's Stock Option Plan provide that, to the fullest
extent permitted by the Company's Articles of Incorporation and Bylaws and by
Utah law, no member of the committee which administers the plan will be liable
for any action or omission taken with respect to the plan or any options issued
thereunder. The Plan also provides that no member of the Board of Directors will
be liable for any action or determination made in good faith with respect to the
Plan or any option granted thereunder.
 
     There is no pending litigation or proceeding involving a director, officer,
employee or other agent of the Company as to which indemnification is being
sought, nor is the Company aware of any pending or threatened litigation that
may result in claims for indemnification by any director, officer, employee or
other agent.

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES
 
     The Company has entered into five transactions in the past three years
involving the issuance of its securities under certain transactional exemptions
of the Securities Act of 1933.
 
     On February 20, 1996, the Company issued to Laboratoires Fournier 337,837
Common Shares in conversion and satisfaction of a non-interest bearing
$3,000,000 promissory note sold to Laboratoires Fournier in 1993. On November
29, 1996, the Company issued 37,202 Common Shares to CHIC, an affiliate of CHCA,
for a total purchase price of $250,000. In connection with that transaction, on
December 1, 1996, the Company also issued to ACH, a subsidiary of CHCA, a
warrant to acquire up to 44,791 Common Shares at an exercise price of $8.88 per
share. In March 1997, the Company issued two promissory notes (one for $10.0
million and the other for $5.0 million) to Elan and delivered to Elan a warrant
to purchase 104,166 Common Shares in connection with the purchase of certain
technology from Elan. Effective November 1, 1997, the Company issued Novartis
238,541 Common Shares and warrants to acquire 18,750 Common Shares in connection
with the exchange by Novartis of its 20% equity interest in Dermion for an
equity position in the Company pursuant to the provisions of the 1997
Amendments.
 
     In connection with each of these isolated issuances of the Company's
securities, each purchaser of those securities represented and warranted to the
Company that it (i) was aware that the securities had not been registered under
federal securities laws, (ii) acquired the securities for its own account for
investment purposes and not with a view to or for resale in connection with any
distribution for purposes of the federal securities laws, (iii) understood that
the securities would need to be indefinitely held unless registered or an
exemption from registration applied to a proposed disposition, (iv) was aware
that the certificate representing the securities would bear a legend restricting
their transfer, and (v) was aware that there was no public market for the
securities. The Company believes that, in light of the foregoing, and in light
of the sophisticated nature of each of the acquirers, the sale of the Company's
securities to the respective acquirers did not constitute the sale of an
unregistered security in violation of the federal securities laws and
regulations by reason of the exemption provided under sec. 4(2) of the
Securities Act, and the rules and regulations promulgated thereunder.
 
     Concurrently with the closing of the Offering, Elan will acquire, directly
from the Company in private placement transactions, approximately 833,333 Common
Shares (subject to adjustment as described below) for approximately $10.2
million (the amount outstanding under the $10.0 million note) and approximately
$5.1 million of Common Shares at a price per share equal to the initial public
offering price hereunder. Simultaneously with such purchase, the Company will
repay the Elan Notes, including interest thereon. If the initial public offering
price hereunder is less than $12.00 per share, the number of Common Shares that
Elan will have the right to purchase for approximately $10.2 million (the amount
outstanding under the $10.0 million note) will be equal to approximately $10.2
million divided by the initial public offering price hereunder. Elan has
represented in the Elan agreements that it is aware that those Common Shares
will not be registered under federal securities laws, will acquire those Common
Shares for its own account and for investment purposes, understands that the
Common Shares will need to be held indefinitely unless registered or an
exemption from registration applies to any proposed disposition, and that the
certificates representing the shares will bear a restrictive legend. In light of
the foregoing, the Company believes that the acquisition of the approximately
833,333 Common Shares (subject to adjustment under certain circumstances) and
the approximately $5.1 million of Common Shares at a price per share equal to
the initial public offering price hereunder in private placement transactions
will not constitute the sale of an unregistered security in violation of federal
securities law by reason of the exemption provided under sec. 4(2) of the
Securities Act.

ITEM 17. UNDERTAKINGS
 
     The undersigned Registrant hereby undertakes that:
 
          (1) The undersigned registrant hereby undertakes to provide to the
     underwriters at the closing specified in the underwriting agreements
     certificates in such denominations and registered in such names as required
     by the underwriters to permit prompt delivery to each purchaser.
 
          (2) Insofar as indemnification for liabilities arising under the
     Securities Act of 1933 may be permitted to directors, officers and
     controlling persons of the registrant pursuant to the foregoing provisions,
     or otherwise, the registrant has been advised that in the opinion of the
     Securities and Exchange Commission such indemnification is against public
     policy as expressed in the Act and is, therefore, unenforceable. In the
     event that a claim for indemnification against such liabilities (other than
     the payment by the registrant of expenses incurred or paid by a director,
     officer or controlling person of the registrant in the successful defense
     of any action, suit or proceeding) is asserted by such director, officer or
     controlling person in connection with the securities being registered, the
     registrant will, unless in the opinion of its counsel the matter has been
     settled by controlling precedent, submit to a court of appropriate
     jurisdiction the question whether such indemnification by it is against
     public policy as expressed in the Act and will be governed by the final
     adjudication of such issue.
 
          (3) For purposes of determining any liability under the Securities Act
     of 1933, the information omitted from the form of prospectus filed as part
     of this registration statement in reliance upon Rule 430A and contained in
     a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or
     (4), or 497(h) under the Securities Act shall be deemed to be part of this
     registration statement as of the time it was declared effective.
 
          (4) For the purpose of determining any liability under the Securities
     Act of 1933, each post-effective amendment that contains a form of
     prospectus shall be deemed to be a new registration statement relating to
     the securities offered therein, and the offering of such securities at that
     time shall be deemed to be the initial bona fide offering thereof.

     RE:  IOMED, INC.
          REGISTRATION STATEMENT ON FORM S-1
          (REGISTRATION NO. 333-37159)


Gentlemen:

          We are acting as counsel to IOMED, Inc., a Utah corporation (the
"Company"), in connection with the preparation of the above-referenced
Registration Statement on Form S-1 (the "Registration Statement"), filed by the
Company with the Securities and Exchange Commission (the "Commission") on
October 3, 1997. The Registration Statement relates to the registration under
the Securities Act of 1933, as amended (the "Act"), of up to 1,700,000 common
shares (the "Shares") of no par value, to be issued and sold pursuant to an
underwriting agreement to be entered into among the Company and EVEREN
Securities, Inc., Hanifen, Imhoff Inc. and Wedbush Morgan Securities, on behalf
of themselves and the several other underwriters to be named in Schedule I
thereto (the "Underwriting Agreement"). Capitalization terms used herein and not
otherwise defined have the meanings given to them in the Registration Statement.

          This opinion is delivered in accordance with the requirements of Item
601(b)(5) of Regulation S-K promulgated under the Act.

          In connection with this opinion, we have examined and are familiar
with originals or copies, certified or otherwise identified to our satisfaction,
of (i) the Amended and Restated Articles of Incorporation of the Company; (ii)
the By-laws of the Company as amended to date;

(iii) certain resolutions and written consents of the Board of Directors of the
Company relating to the offering of the Shares; (iv) the Registration
Statement, and (v) such other documents as we have deemed necessary or
appropriate as the basis for the opinions set forth below. In such examination,
we have assumed the genuineness of all signatures, the legal capacity of
natural persons, the authenticity of all documents submitted to us as
originals, the conformity to original documents of all documents submitted to
us as certified or photostatic copies and the authenticity of the originals of
such latter documents. As to any facts material to this opinion which we did
not independently establish or verify, we have relied upon statements and
representations of officers and other representatives of the Company and others.

        Members of our firm are admitted to the practice of law in the State of
Utah, and we express no opinion as to the laws of any other jurisdiction.

        Based upon and subject to the foregoing, we are of the opinion that
when (i) the Registration Statement becomes effective, (ii) the Underwriting
Agreement is duly executed and delivered by the Company and the other parties
thereto and (iii) certificates representing the Shares are duly executed,
countersigned, registered and duly delivered upon payment of the agreed upon
consideration therefor, the Shares will be duly authorized, validly issued,
fully paid and non-assessable.

        We hereby consent to the filing of this opinion with the Commission as
Exhibit 5.1 to the Registration Statement. We also consent to the reference to
our firm under the caption "Legal Matters" in the Registration Statement. In
giving this consent, we do not thereby admit that we are included in the
category of persons whose consent is required under Section 7 of the Act or the
rules and regulations of the Commission.

                                        Very truly yours,

ARTICLE II: THE LICENSE

1.1.  ELAN shall remain proprietor of all the ELAN IONTOPHORETIC INTELLECTUAL
      PROPERTY but hereby grants to IOMED for the term of the Agreement an
      exclusive (including as to ELAN) license in the TERRITORY, with the right
      to grant sublicenses pursuant to and in accordance with the provisions of
      Article II Paragraph 2, to research develop, manufacture, have
      manufactured for IOMED (or its permitted sublicenses), use, sell and
      otherwise commercialize the ELAN IONTOPHORETIC INTELLECTUAL PROPERTY and
      the PRODUCTS in the FIELD under the terms and conditions set out herein.
      The exclusive nature of the licenses granted by ELAN are subject to 
      **** as set out in Appendix C.  ELAN's license to IOMED shall specifically
      exclude ELAN EXCLUDED TECHNOLOGY.

1.2.  Subject to earlier termination of the Agreement pursuant to Article VIII,
      at the end of the ADDITIONAL TERM the rights granted by ELAN to IOMED
      pursuant to Paragraph 1.1 above shall be exclusive, paid-up and
      irrevocable.

2.1.  IOMED may sublicense rights which incorporate the ELAN IONTOPHORETIC
      INTELLECTUAL PROPERTY ****, without the prior written consent of ELAN.
<PAGE>   9
2.2.  Any sublicense other than permitted by paragraph 2.1. above, ****, shall
      require the prior written consent of ELAN, which may be withheld in the
      sole discretion of ELAN.

2.3.  No sublicense granted by IOMED pursuant to Article II Paragraph 2 shall
      authorize or permit the sublicense to grant further sublicenses ****.
      IOMED shall use its reasonable endeavors to ensure that ELAN shall have
      the same rights of audit and inspection vis a vis the sublicensee as ELAN
      has pursuant to this Agreement concerning IOMED.

2.4.  Insofar as the obligations owed by IOMED to ELAN are concerned, IOMED
      shall remain responsible for all acts and omissions of any sublicenses as
      if such acts and omissions were by IOMED; provided that no such acts or
      omissions of such sublicensee will constitute a material breach by IOMED
      for the purpose of Article VIII Paragraph 3.  In the event that ELAN
      terminates the Agreement pursuant to the provisions of Article VIII
      Paragraph 3, due to the default of IOMED, then ELAN shall, with IOMED's
      consent and assistance, notify each sublicensee appointed pursuant to
      Article II Paragraphs 2.1. and 2.2. of its termination.  If any
      sublicensee elects to notify ELAN that it requires the continuation of the
      licenses granted to IOMED pursuant to this Agreement, ELAN shall promptly
      enter into good faith negotiations with sublicensee to establish a direct
      contractual nexus between ELAN and such sublicensee.  Such contractual
      nexus shall, subject to ELAN's reasonable discretion, be on commercially
      reasonable terms and shall to the extent practicable be on terms no less
      favorable to the sublicensee than the terms of such sublicensees'
      agreement with IOMED, and shall provide that the sublicensee shall take
      over the applicable obligations owed by IOMED to ELAN pursuant to this
      Agreement.  Sales of PRODUCTS and other consideration payable to such a
      sublicensee in relation to the PRODUCTS shall constitute NET REVENUES for
      the purpose of calculating the sums payable by the sublicensee to ELAN.
      ****.

3.    It is contemplated that the physical transfer of the ELAN IONTOPHORETIC
      KNOW-HOW to be licensed under this Agreement and the furnishing of copies
      of relevant patent documentation regarding the ELAN IONTOPHORETIC PATENT
      RIGHTS shall be completed within six months of the EFFECTIVE DATE.  ELAN
      shall, at its expense, provide all reasonable assistance within such
      six-month period to IOMED to facilitate such transfer, provided, that in
      the event that IOMED's requirements relating to such transfer are in
      excess of the Parties' current reasonable, good faith, expectations, the
      Parties shall negotiate in good faith reimbursement of ELAN's
      out-of-pocket expenses.  Any dispute under this Paragraph 3 shall be
      resolved by referring such dispute to an arbitrator pursuant to the
      provisions of Article IX Paragraph 14.

4.    Insofar as the exercise by IOMED and its permitted sublicensees of the
      ELAN IONTOPHORETIC INTELLECTUAL PROPERTY rights is concerned, and to the

      agrees that during the TERM and the ADDITIONAL TERM ELAN shall not cite or
      otherwise rely upon the patents licensed by ELAN from **** pursuant to the
      **** AGREEMENT, or developed jointly by ELAN and **** pursuant to the ****
      AGREEMENT, against IOMED or IOMED's sublicensees and ELAN shall use its
      commercially reasonable endeavors to ensure that ELAN's sublicensees of
      the **** TECHNOLOGY shall be bound in similar fashion.  ELAN shall be
      entitled to disclose such CONFIDENTIAL INFORMATION as ELAN considers
      reasonably necessary in using such commercially reasonable endeavors to
      potential sublicensees under obligations of confidentiality.  As of the
      date hereof (I) ELAN has no such sublicensees and (II) to the knowledge of
      ELAN, there are currently no grounds to cite such patents and there are no
      express provisions of the **** AGREEMENT requiring ELAN to cite such
      patents,

      otherwise reasonably communicate to the trade concerning the existence of

      and in accordance with the provisions of such agreement and subject to
      the provisions of any product-specific sublicense agreements entered into
      by ELAN, including the agreement referred to in Article II Paragraph 10.
      During the Negotiation Period, the Parties shall negotiate in good faith
      the terms of a sublicense. It is agreed that this paragraph creates no
      legal obligation upon either Party to conclude the sublicense agreement,
      but merely evidences an intention on the part of both Parties to proceed

2.2.  In further consideration of the license of the ELAN IONTOPHORETIC PATENT
      RIGHTS to IOMED, subject to the proviso in this Paragraph 2.2, ELAN shall
      not be entitled to a royalty on NET REVENUES, whether generated on or
      after 1st July 1997 or otherwise, (a) in connection with PRODUCTS whose
      primary purpose is for inducing local anaesthesia and/or (b) in
      connection with PRODUCTS for treating local acute inflammatory
      conditions, whether or not such products are currently marketed, or in
      development and including improvements thereto; provided that on a
      country by country basis if the research, development, manufacture or
      commercialisation of such PRODUCTS would infringe the ELAN IONTOPHORETIC
      PATENT RIGHTS and/or the DDS IONTOPHORETIC PATENT RIGHTS (but for the
      granting of the licenses by ELAN pursuant to Article II Paragraph 1.1.
      and the licenses granted by DDS pursuant to the DDS AGREEMENT) the
      royalty payable by IOMED to ELAN shall be three per cent (3%) of NET
      REVENUES generated on or after 1st July 1997. IOMED shall not be required
      to pay a royalty to ELAN of NET REVENUES on commercialisation of the
      products listed in Appendix D hereto which, the Parties acknowledge, are
      presently-marketed products of IOMED. In the event of any dispute
      relating to the foregoing provisions of this Paragraph, the Parties shall
      cause such dispute to be arbitrated before an experienced patent
      attorney. In such event the procedure set forth in Article VIII Paragraph
      14 shall to the extent practicable apply to the conduct of such
      arbitration.

2.3.  In the event that the Parties conclude a sublicense to or for the AQI
      TECHNOLOGY as set out in Article II Paragraph 9,then notwithstanding any
      other provisions of the terms of such sublicense to be agreed between the
      Parties, including the license royalty, IOMED shall pay to Elan
      International Services Limited, or such other AFFILIATE as currently
      holds the applicable rights pursuant to the AQI AGREEMENT, a royalty of
      seven and one half per cent (7.5%) of the NET REVENUES derived by IOMED
      from the third party referred to in Article II Paragraph 10 for a term to
      be agreed.

2.4.  IOMED shall not discriminate in its commercialization strategy and pricing
      policy as between the PRODUCTS referred to in Article IV Paragraphs 2.1.
      and 2.2.

2.5.  The Parties agree that when IOMED provides free samples of PRODUCT to
      promote the further sale of PRODUCTS, such provision of free samples
      shall not generate any royalty payments to ELAN by IOMED, its and/or
      sublicensees; provided however, that such sampling is specifically
      designed to promote sales of PRODUCT and is no less favorable to ELAN
      than IOMED's standard sampling practice for similar products.

Royalty Payments, Reports and Records

3.1.  Within forty five (45) days of the end of each quarter, IOMED shall notify
      ELAN of the NET REVENUES of each of the PRODUCTS and arising from the

      hereof and shall deliver to ELAN a written statement thereof within forty
      five (45) days following the and of each calendar quarter (or any past
      thereof in the first or last calendar quarter of this Agreement) for such
      calendar quarter. Said written statements shall set forth (I) for each
      PRODUCT on ****, the calculation of NET REVENUES from gross revenues
      during that calendar quarter, the applicable percentage royalty rates, and
      a computation of such royalties due and (II) such details of the
      transactions arising from the exploitation of the ELAN IONTOPHORETIC
      INTELLECTUAL PROPERTY and/or the IOMED PATENT RIGHTS and/or the IOMED
      KNOW-HOW as are relevant to the calculation of NET REVENUES (the "Royalty
      Statement").

3.3.  AU payments due hereunder shall be made in United States Dollars.
      Payments due on NET REVENUES received in a currency other than United
      States Dollars shall first be calculated in the foreign currency and then
      converted to United States Dollars on the basis of the average of the
      exchange rates in effect for the purchase of United States Dollars with
      such foreign currency quoted in the Wall Street Journal (or comparable
      publication if not quoted in the Wall Street Journal) with respect to the
      currency of the country or origin of such payment for the last business
      day of each month for which the payment is being made.

3.4.  ELAN shall have the right to have access, on reasonable notice, to IOMED's
      or IOMED's sublicensee's financial documentation and records during
      reasonable business hours for the purpose of verifying the royalties
      payable as provided in this Agreement for the two preceding years.  This
      right may not be exercised more than once in any calendar year, and once a
      calendar year is audited it may not be reaudited.  For the avoidance of
      doubt, the Parties agree that all information furnished to ELAN pursuant
      to this Paragraph shall constitute CONFIDENTIAL INFORMATION for the
      purposes of this Agreement.

      Any adjustment required by such inspection shall be made within thirty
      (30) days of the agreement of the Parties or, if not agreed, upon the
      determination of an arbitrator to whom any dispute under this Paragraph
      shall be submitted to arbitration pursuant to Article IX Paragraph 14.  If
      the adjustment payable to ELAN is greater than ****, then the cost to ELAN
      for the inspection and if applicable the arbitration she be paid by IOMED.
      In addition, IOMED shall pay interest to ELAN at **** (applicable as of
      the date on which payment should have been made pursuant to Article IV
      Paragraph 3.3.), from the date on which payment should have been made
      pursuant to Article IV paragraph 3.3. until the date of payment.

      filing and prosecuting all NDAs and other applications for regulatory
      approvals.  ELAN shall transfer the INDs held by it in relation to the
      PRODUCTS.  IOMED or its sublicensees shall file the NDAs with the FDA and
      will use its reasonable efforts in prosecuting said NDA to approval.
      IOMED shall thereafter maintain at its own cost the NDAs with the FDA for
      the term of this Agreement.  Subject to IOMED's reasonable discretion
      IOMED hereby agrees to provide to ELAN at ELAN's own cost access to such
      NDAs as ELAN reasonably requests.  ****.  For the avoidance of doubt,
      the parties agree that all information furnished to ELAN pursuant to this
      Paragraph shall Institute CONFIDENTIAL INFORMATION for the purposes of

2.    It is hereby acknowledged that there are inherent uncertainties involved
      in the development and registration of pharmaceutical products with the
      FDA or any other regulatory body in the TERRITORY insofar as obtaining
      approval is concerned and such uncertainties form part of the business
      risk involved in undertaking the form of commercial collaboration as set
      forth in this Agreement.

          ELAN IONTOPHORETIC PATENT RIGHTS and to file patent applications
          covering any improvements, to prosecute and defend such applications
          against independent third party oppositions; and upon grant of any
          letters patent covering such invention, to maintain such letters
          patent in force. IOMED at its expense shall have the right to control
          such filing, prosecution, defence and maintenance; provided however
          ELAN shall be provided with copies of all substantive documents
          relating to such filing, prosecution and defence in sufficient time to
          review such documents and comment thereon prior to any deadline for
          filing the same, if desired by ELAN. IOMED shall be entitled to

          documents, forms and declarations and otherwise co-operate fully to
          enable IOMED to seek and obtain the broadest protection afforded by
          the patent laws of the countries within the TERRITORY, whether during
          the TERM of this Agreement or thereafter. For the avoidance of doubt,
          the Parties agree that all information furnished to ELAN pursuant to
          this Paragraph shall constitute CONFIDENTIAL INFORMATION for the
          purposes of this Agreement.

2.2.      If IOMED does not intend to make an application for patents or

          and the right to apply for patents or other intellectual property
          protection in respect thereof (in the countries where IOMED has not
          applied). If IOMED does not intend to continue prosecution of a

          obtained by ELAN pursuant to this Paragraph shall constitute ELAN 
          IONTOPHORETIC PATENT RIGHTS.

2.3       ELAN shall use its commercially reasonable endeavours to ensure that
          the inventors of the ELAN IONTOPHORETIC PATENT RIGHTS shall be

          execute documents, relating to the filing, prosecution and defence of
          the ELAN IONTOPHORETIC PATENT RIGHTS.

2.4. IOMED shall not abandon an ELAN IONTOPHORETIC PATENT RIGHT without the
     prior written consent of ELAN, which shall not be unreasonably withheld. In
     the event that the Parties agree that IOMED may abandon such an ELAN
     IONTOPHORETIC PATENT RIGHT, ELAN shall have the right to take over the
     prosecution and maintenance of such ELAN IONTOPHORETIC PATENT RIGHTS, which
     rights shall no longer form a part of and be covered by the licenses
     granted by ELAN pursuant to this Agreement.

3.   IOMED and ELAN shall promptly inform the other in writing of any alleged
     infringement of which it shall become aware by a third party of any patents
     within the ELAN IONTOPHORETIC PATENT RIGHTS and provide such other with any
     available evidence of infringement.

4.   During the TERM and the ADDITIONAL TERM, IOMED shall have the right to

     the ELAN IONTOPHORETIC PATENT RIGHTS and/or the IOMED PATENT RIGHTS. ELAN
     shall agree to be named as a necessary party in an action brought by and
     fully financed by IOMED and will reasonably co-operate with such action.
     Any expenses borne by ELAN shall be reimbursed by IOMED. Any recovery
     remaining after the deduction by IOMED of the reasonable expenses
     (including attorney's fees and expenses) incurred in relation to such an
     infringement proceeding shall constitute NET REVENUES for the purpose of
     this Agreement. Should IOMED decide not to pursue such infringers of the
     ELAN IONTOPHORETIC PATENT RIGHTS, ELAN may do so at its expense and for its
     own benefit, and IOMED will reasonably co-operate with such action. Any
     expenses borne by IOMED in co-operating with such action shall be

ARTICLE VIII: TERM AND TERMINATION

1.   This Agreement is concluded for a period commencing as of the date of this

included in the ELAN IONTOPHORETIC PATENT RIGHTS and the DDS IONTOPHORETIC
PATENT RIGHTS which are used in the exploitation of the PRODUCTS, whichever is
longer ("the TERM"). From and after the tenth year of the TERM, in the event
that IOMED reasonably believes that there are ELAN IONTOPHORETIC PATENT
RIGHT(s) that are not used in connection with the exploitation of the PRODUCTS,
IOMED shall provide written notice thereof to ELAN, setting forth in reasonable
detail its reasons therefor.

Elan and IOMED shall thereupon each in good faith attempt to make a joint
determination of whether IOMED's conclusion is correct or if such ELAN
IONTOPHORETIC PATENT RIGHT(S) are in fact used in connection with such
exploitation; if the Parties are unable to agree upon such joint determination
within 90 days of such notice from IOMED, either party shall have the right to
have such matter arbitrated. Such arbitration shall be conducted before an
independent patent attorney reasonably selected by the Parties, or on such
other basis as shall be mutually reasonably agreeable, pursuant to the
provisions of Article IX Paragraph 14.

2.    In addition, for a period of five years commencing upon the expiration of
      the TERM ("the ADDITIONAL TERM"), the licenses granted by ELAN pursuant to
      Article II shall continue, provided, that the royalties payable during the
      ADDITIONAL TERM to ELAN referred to in Article IV shall be fifty percent
      (50%) of the amount otherwise payable during the TERM; thereafter, IOMED
      shall have an exclusive paid-up royalty-free license to the ELAN
      IONTROPHORETIC KNOW-HOW.

3.    In addition to the rights of early or premature termination provided for
      elsewhere in this Agreement, in the event that any of the term or
      provisions hereof are incurably breached by either Party, the
      non-breaching Party may immediately terminate this Agreement by written
      notice.  An incurable breach shall be committed when either Party is
      dissolved, liquidated, discontinued, becomes insolvent or when any
      proceeding is filed or commenced by either Party under bankruptcy,
      insolvency or debtor relief laws (and not dismissed within ninety (90)
      days).  Subject to the other provisions of this Agreement in the event of
      any other material breach, the non-breaching Party may terminate this
      Agreement by the giving of written notice to the breaching Party that this
      Agreement will terminate on the ninetieth (90th) day from notice unless
      cure is sooner effected.  If the breaching Party has proposed a course of
      action to rectify the breach and is acting in good faith to rectify same
      but has not cured the breach by the ninetieth (90th) day, the said period
      shall be extended by such period as is reasonably necessary to permit the
      breach to be rectified.  In the event that a Party is entitled to
      terminate this Agreement, such Party shall also be entitled to terminate
      the DDS AGREEMENT.  Furthermore in the event that a Party is entitled to
      terminate the DDS AGREEMENT, such Party shall also be entitled to
      terminate this Agreement.  In the event that the breaching Party disputes
      the validity of the of the right of the non-breaching Party to terminate
      the Agreement pursuant to this Paragraph, either Party may refer the
      dispute to an arbitrator pursuant to the provisions of Article IX
      Paragraph 14. Pending the determination of the arbitrator, neither Party
      may regard the Agreement as having been terminated and in particular shall
      not allege or claim to any third party that the Agreement has been
      terminated pursuant to this Paragraph.

4.    In the event that IOMED elects to proceed against ELAN for damages in
      circumstances where IOMED would have been entitled to terminate the
      Agreement pursuant to Article IX Paragraph 3 and IOMED obtains a final
      order for damages from a court of competent jurisdiction which is not
      subject of further appeal, IOMED may offset the said order for damages
      against sums otherwise due to ELAN pursuant to Article IV until recovery
      of the said judgment.

            Party hereto from any liability which, at the time of such
            termination has already accrued to the other Party or which is
            attributable to a period prior to such termination nor preclude
            either party from pursuing all rights and remedies it may have
            hereunder or at law or in equity with respect to any breach of this
            Agreement;

1.1.  Each of the parties agrees, during the TERM and the ADDITIONAL TERM, to
      hold in confidence and not disclose to any third parties, including any of
      the OFFERING PARTIES, except to the extent required by applicable law or
      administrative or judicial process, the ELAN IONTOPHORETIC INTELLECTUAL
      PROPERTY or the contents or nature thereof, provided, that the foregoing
      covenant shall not be applicable to ELAN in the event that the foregoing
      covenant shall not be applicable to ELAN in the event that IOMED (i)
      abandons or (ii) ceases to develop or commercialize (and provides notice
      thereof to ELAN) any such ELAN IONTOPHORETIC INTELLECTUAL PROPERTY and
      ELAN determines subsequently to develop products or technologies based on
      such ELAN IONTOPHORETIC INTELLECTUAL PROPERTY, irrespective of whether it
      is reduced to patent.


     
<PAGE>   25




      Each Party may make such disclosure to its directors, officers and agents
      and, in the case of IOMED, its potential and actual sublicensees and other
      parties to whom such disclosure is appropriate to enable IOMED to conduct
      its regular business (each of whom shall be bound by IOMED's disclosure
      agreements), who shall be informed of such confidentiality obligation and
      for whose breach the disclosing party shall be responsible.

1.2.  Subject to the provisions of Paragraph 1. 1., any whether written or oral
      (oral information shall be reduced to writing within one month by the
      Party giving the oral information and the written form shall be furnished
      to the other Party) pertaining to the ELAN IONTOPHORETIC INTELLECTUAL
      PROPERTY or the PRODUCTS that has been or will be communicated or
      delivered by ELAN to IOMED, and any information from time to time
      communicated or delivered by IOMED to ELAN, including without limitation,
      trade secrets, business methods, and cost, supplier, manufacturing and
      customer information, shall be treated by IOMED and ELAN, respectively, as
      CONFIDENTIAL INFORMATION, and shall not be disclosed or revealed to any
      third Party whatsoever or used in any manner except as expressly provided
      for  herein; provided, however, that such CONFIDENTIAL INFORMATION shall
      not be subject to the restrictions and prohibitions set forth in this
      section to the extent that such CONFIDENTIAL INFORMATION:

      1.2.1.  is available to the public in public literature or otherwise, or
              after disclosure by one Party to the other becomes public
              knowledge through no default of the Party receiving such
              information; or

      1.2.2.  was known to the Party receiving such information prior to the
              receipt of such information by such Party, whether received before
              or after the date of this Agreement; or

      1.2.3.  is obtained by the Party receiving such information from a third
              party not subject to a requirement of confidentiality with respect
              to such information; or

      1.2.4.  is required to be disclosed pursuant to: (A) any order of a court
              having jurisdiction and power to order such information to be
              released or made public; or (B) other requirement of law, provided
              that if the receiving Party becomes legally required to disclose
              any CONFIDENTIAL INFORMATION, the receiving Party shall give the
              disclosing Party prompt notice of such fact so that the disclosing
              Party may obtain a protective order or other appropriate remedy
              concerning any such disclosure.


             
<PAGE>   26




              The receiving Party shall fully cooperate with the disclosing
              Party in connection with the disclosing Party's efforts to obtain
              any such order or other remedy.  If any such order or other remedy
              does not fully preclude disclosure, the receiving Party shall make
              such disclosure only to the extent that such disclosure is legally
              required; or

      1.2.5.  is independently developed by or for the Party by persons not
              having access to the CONFIDENTIAL INFORMATION of the other Party.

1.3.  Each Party shall take all such precautions as it normally takes with its
      own CONFIDENTIAL INFORMATION to prevent any improper disclosure of such
      CONFIDENTIAL INFORMATION to any third Party, provided however, that such
      CONFIDENTIAL INFORMATION may be disclosed within the limits required to
      obtain any authorization from the FDA or any other United States of
      America or foreign governmental or regulatory agency or, with the prior
      written consent of the other Party, which shall not be unreasonably
      withheld, or as may otherwise be required in connection with the purposes
      of this Agreement.

1.4.  IOMED agrees that it will not use, directly or indirectly, any ELAN
      IONTOPHORETIC INTELLECTUAL PROPERTY, or other CONFIDENTIAL INFORMATION
      disclosed to IOMED or obtained from ELAN pursuant to this Agreement, other
      than as expressly provided herein.  ELAN agrees that it will not use,
      directly or indirectly, any IOMED KNOW-HOW, IOMED PATENT RIGHTS or other
      CONFIDENTIAL INFORMATION disclosed to ELAN or obtained from IOMED pursuant
      to this Agreement, other than as expressly provided herein.

1.5   IOMED and ELAN will not publicize the existence of this Agreement in any
      way without the prior written consent of the other subject to the
      disclosure requirements of applicable laws and regulations.  In the event
      that either Party wishes to make an announcement concerning the Agreement,
      that Party will seek the consent of the other Party.  The terms of any
      such announcement shall be agreed in good faith.

2.    Assignments/Subcontracting

      IOMED may not assign (other than by operation of law in the event of an
      acquisition of IOMED, or a merger or similar transaction, subject to the
      provisions as set forth in Article IX  Paragraph 3) the rights licensed by
      ELAN under Article II without the prior written consent of ELAN, which may
      be withheld in ELAN's sole discretion.  ELAN shall be entitled to assign
      its rights and obligations to an AFFILIATE.

    
<PAGE>   27





      ELAN may not assign to an unaffiliated third party (other than by
      operation of law in the event of an acquisition of ELAN, or a merger or
      similar transaction) its rights under this Agreement without the prior
      written consent of IOMED, which may be withheld in IOMED's sole
      discretion.

3.    Certain Changes of Control.

      In the event that an OFFERING PARTY makes or signifies its intention of
      make a bona fide offer which would result in such a party owning,
      directly or indirectly, more than fifteen per cent (15%) of IOMED's
      voting stock, on a fully-diulted basis, or otherwise controlling the
      IOMED's Board of Directors, or otherwise obtains substantial contractual
      rights pursuant to an agreement with IOMED to the ELAN IONTOPHORETIC
      INTELLECTUAL PROPERTY (as reasonably determined by ELAN) (each, a
      "Control Transaction"), IOMED shall (x) not accept such offer until it
      shall have complied with the remaining provision of this Paragraph
      without ELAN's consent (in its sole discretion) and (y) advise the
      appropriate OFFERING PARTY that, in lieu of IOMED accepting such offer,
      such OFFERING PARTY should make a separate offer with respect to that
      portion of IOMED's business that relates to the FIELD, and not to the
      remaining portion of IOMED's business. ELAN shall have a period of thirty
      (30) days to conduct appropriate due diligence and to determine whether
      it desires to match an offer made by an OFFERING PARTY with respect to
      that portion of IOMED's business that relates to the FIELD, (including
      the same economic, payment and other terms); it being understood that
      IOMED shall make available to ELAN reasonable and sufficient information
      to enable ELAN to conduct such due diligence.

      In the event that ELAN determines to make such offer, IOMED shall accept
      ELAN's offer and expeditiously consummate such transaction with ELAN.
      Notwithstanding the foregoing, in the event that an OFFERING PARTY
      consummates a Control Transaction without the consent of the IOMED's
      Board of Directors (as such Board is comprised at the time such
      transaction is first publicly announced or commenced) (including without
      limitation, in connection with a tender offer or offers or proxy
      solicitation), ELAN shall have the right in its sole discretion, to
      terminate the licences granted by ELAN pursuant to this Agreement,
      without payment or penalty to IOMED.

4.    Parties bound

      This Agreement shall be binding upon and enure for the benefit of Parties
      hereto, their successors and permitted assigns.

5.    Severability

      If any provision in this Agreement is agreed by the Parties to be, or is
      deemed to be, or becomes invalid, illegal, void or unenforceable under any
      law that is applicable hereto, (i) such provision will be deemed amended
      to conform to applicable laws so as to be valid and enforceable or, if it
      cannot be so amended without materially altering the intention of the
      Parties, it will be deleted, with effect from the date of such agreement
      or such earlier date as the Parties may agree, and (ii) the validity,
      legality and enforceability of the remaining provisions of this Agreement
      shall not be impaired or affected in any way.

6.    Force Majeure

      Neither Party to this Agreement shall be liable for delay in the
      performance of any of its obligations hereunder if such delay results from
      cause beyond its reasonable control, including, without limitation, acts
      of God, fires, strikes, acts of war, or intervention of a Government
      Authority, non-availability of raw materials, but any such delay or
      failure shall be remedied by such Party as soon as practicable.

7.    Relationship of the Parties

      Nothing contained in this Agreement is intended or is to be construed to
      constitute ELAN and IOMED as partners or joint venturers or either Party
      as an employee of the other.  Neither Party hereto shall have any express
      or implied right or authority to assume or create any obligations on
      behalf of or in the name of the other Party or to bind the other Party to
      any contract, agreement or undertaking with any third party

8.    Amendments

      No amendment, modification or addition hereto shall be effective or
      binding on either Party unless set forth in writing and executed by a duly
      authorized representative of both Parties.

9.    Waiver

      No waiver of any right under this Agreement shall be deemed effective
      unless contained in a written document signed by the Party charged with
      such waiver, and no waiver of any breach or failure to perform shall be
      deemed to be a waiver of any future breach or failure to perform or of any
      right arising under this Agreement.

      Any dispute under this Agreement which is not settled by mutual consent
      and which is the subject of an arbitration clause shall be finally settled
      by binding arbitration conducted in accordance with the Commercial
      Arbitration Rules of the American Arbitration Association by an arbitrator
      appointed in accordance with said rules.  The arbitration shall be held in
      New York, New York and the arbitrator shall be to the extent practicable

      expert in pharmaceutical product development and marketing (including
      clinical development and regulatory affairs) or an independent patent
      attorney as the case may be.  The arbitrator shall determine what
      discovery will be permitted, consistent with the goal of limiting the cost
      and time which the Parties must expend for discovery; provided the
      arbitrator shall permit such discovery as he deems necessary to permit an
      equitable resolution of the dispute.  Any written evidence originally in a
      language other than English shall be submitted in English translation
      accompanied by the original or a true copy thereof.  The costs of the
      arbitration, including administrative and arbitrator's fees, shall be
      shared equally by the Parties and each Party shall bear its own costs and
      attorneys' and witness' fees incurred in connection with the arbitration,
      provided that the prevailing Party may be awarded the reasonable costs and
      fees incurred in connection with the arbitration at the discretion of the
      arbitrator.


<PAGE>   31




      A disputed performance or suspended performance pending the resolution of
      the arbitration must be completed within thirty (30) days following the
      final decision of the arbitrators or such other reasonable period as the
      arbitrators determine in a written opinion.  Any arbitration subject to
      this Paragraph 14 shall be completed within one (1) year from the filing
      of notice of a request for such arbitration.  The arbitration proceedings
      and the decision shall not be made public without the joint consent of the
      Parties and each Party shall maintain the confidentiality of such
      proceedings and decision unless (a) otherwise permitted by the other Party
      or (b) otherwise required by the applicable law in which case the
      provisions of Article IX Paragraph 1.2.4. shall be applicable.  The
      Parties agree that the decision shall be the sole, exclusive and binding
      remedy between them regarding any and all disputes, controversies, claims
      and counterclaims presented to the arbitrators. Application may be made to
      any court having jurisdiction over the Party (or its assets) against whom
      the decision is rendered for a judicial recognition of the decision and an
      order of enforcement.

15.   Withholding

      Any income or other taxes which IOMED is required by law to pay or
      withhold on behalf of ELAN with respect to royalties and any other moneys
      payable to ELAN under this Agreement shall be deducted from the amount of
      such royalties and moneys due.  IOMED shall furnish ELAN with proof of
      such payments.  Any such tax required to be paid or withheld shall be an
      expense of and borne solely by ELAN.  IOMED shall promptly provide ELAN
      with a certificate or other documentary evidence to enable ELAN to support
      a claim for a refund or a foreign tax credit with respect to any such tax
      so withheld or deducted by IOMED.  Both Parties will reasonably cooperate
      in completing and filing documents required under the provisions of any
      applicable tax treaty or under any other applicable law, in order to
      enable IOMED to make such payments to ELAN without any deduction or
      withholding.

16.   Indemnity

16.1. ELAN shall indemnify, defend and hold harmless IOMED from all actions,
      losses, claims, demands, damages, costs and liabilities (including
      reasonable attorneys' fees) to which IOMED is or may become subject
      insofar as they arise out of or are alleged or claimed to arise out of any
      breach by ELAN of any of its obligations under this Agreement or
      warranties of ELAN.


<PAGE>   32



16.2. IOMED shall indemnify, defend and hold harmless ELAN from all actions,
      losses, claims, demands, damages, costs and liabilities (including
      reasonable attorneys' fees) to which ELAN is or may become subject
      insofar as they arise out of or are alleged or claimed to arise out of
      any breach by IOMED of any of its obligations under this Agreement or
      warranties of IOMED. IOMED shall assume the sole and entire
      responsibility and shall indemnify and save harmless ELAN from any and
      all claims, liabilities, expenses, including reasonable attorney's fees,
      responsibilities and damages by reason of any claim, proceedings, action,
      liability or injury arising out of any defect in the PRODUCTS, including
      the manufacture, transport, packaging, storage, handling, distribution,
      marketing or sale of the PRODUCTS by IOMED.

16.3. As a condition of obtaining an indemnity in the circumstances set out
      above, the Party seeking an indemnity shall:

      16.3.1  fully and promptly notify the other Party of any claim or
              proceeding, or threatened claim or proceeding;

      16.3.2. permit the indemnifying Party to take full care and control of
              such claim or proceeding;

      16.3.3. assist in the investigation and defence of such claim or
              proceeding;

      16.3.4. not compromise or otherwise settle any such claim or proceeding
              without the prior written consent of the other Party, which
              consent shall not be unreasonably withheld; and

      16.3.5. take all reasonable steps to mitigate any loss or liability in
              respect of any such claim or proceeding.

16.4. Notwithstanding anything to the contrary in this Agreement, ELAN and IOMED
      shall not be liable to the other by reason of any representation or
      warranty, condition or other term or any duty of common law, or under the
      express terms of this Agreement for any consequential or incidental loss
      or damage (whether for loss of profit or otherwise) and whether occasioned
      by the negligence of the respective Parties, their employees or agents or
      otherwise.

ARTICLE II: THE LICENSE

1.1.  DDS shall remain Proprietor of all the DDS IONTOPHORETIC PATENT RIGHTS but
      hereby grants to IOMED for the term of the Agreement an exclusive
      (including as to DDS) license in the TERRITORY, with the right to grant
      sublicenses pursuant to and in accordance with the provisions of Article
      II Paragraph 2, to research, develop, manufacture, have manufactured for
      IOMED (or its permitted sublicensees), use, sell and otherwise
      commercialize the DDS IONTOPHORETIC PATENT RIGHTS and the PRODUCTS in the
      FIELD under the terms and conditions set out herein.

1.2.  Subject to earlier termination of the Agreement pursuant to Article VIII,
      at the end of the ADDITIONAL TERM the rights granted by DDS to IOMED 
      pursuant to Paragraph 1.1 above shall be exclusive, paid-up and 
      irrevocable.

2.1.  IOMED may sublicense rights which incorporate the DDS IONTOPHORETIC PATENT
      RIGHTS ****, without the prior written consent of DDS .

2.2.  Any sublicense other than permitted by Paragraph 2. 1. above, ****,

<PAGE>   8
2.3.  NO sublicense granted by IOMED pursuant to Article II Paragraph 2 shall
      authorize or permit the sublicensee to grant further sublicenses ****,
      IOMED shall use its reasonable endeavors to ensure that DDS shall have the
      same rights of audit and inspection vis a vis the sublicensee as DDS has
      pursuant to this Agreement concerning IOMED.

2.4.  Insofar as the obligations owed by IOMED to DDS are concerned, IOMED shall
      remain responsible for all acts and omissions of any sublicensee as if
      such acts and omissions were by IOMED; provided that no such acts or
      omissions of such sublicensee will constitute a material breach by IOMED

      Paragraph 3, due to the default of IOMED, then DDS shall, with IOMED's

      Article II Paragraphs 2.1 and 2.2 of its termination.  If any sublicensee
      elects to notify DDS that it requires the continuation of the licenses
      granted to IOMED pursuant to this Agreement, DDS shall promptly enter into
      good faith negotiations with such sublicensee to establish a direct
      contractual nexus between DDS and such sublicensee.  Such contractual
      nexus shall subject to DDS's reasonable discretion be on commercially

      favorable to the to the sublicensee than the terms of such sublicensees'
      agreement with IOMED, and shall provide that the sublicensee shall take
      over the applicable obligations owed by IOMED to DDS pursuant to this
      Agreement.  Sales of PRODUCTS and other consideration payable to such a
      sublicensee in relation to the products shall constitute NET REVENUES for
      the purpose of calculating the sums payable by the sublicensee to DDS.  
      ****.

3.    It is contemplated that the furnishing of copies of relevant patent
      documentation regarding the DDS IONTOPHORETIC PATENT RIGHTS shall be
      completed within six months of the EFFECTIVE DATE.

      PATENT RIGHTS in any or some (specifying which) countries of the
      TERRITORY, or fails within six (6) months of disclosure under Article
      VII Paragraph 2.1, to make application in one or more countries of the
      TERRITORY, DDS shall have the option and the right to apply for patents
      or other intellectual property protection in respect thereof (in the
      countries where IOMED has not applied).
<PAGE>   17




      If IOMED does not intend to continue prosecution of a pending application
      in any country of the TERRITORY, IOMED shall promptly inform DDS of such
      a decision and no later than in sufficient time for DDS to continue such
      prosecution. For the avoidance of doubt, the Parties agree that such
      patents as are obtained by DDS pursuant to this Paragraph shall
      constitute DDS IONTOPHORETIC PATENT RIGHTS.

2.3.  DDS shall use its commercially reasonable endeavors to ensure that the
      inventors of the DDS IONTOPHORETIC PATENT RIGHTS shall be reasonably
      available to IOMED to deal with queries, and complete and execute
      documents, relating to the filing, prosecution and defense of the DDS
      IONTOPHORETIC PATENT RIGHTS.

2.4.  IOMED shall not abandon an DDS IONTOPHORETIC PATENT RIGHT without the
      prior written consent of DDS, which shall not be unreasonably withheld.
      In the event that the Parties agree that IOMED may abandon such an DDS
      IONTOPHORETIC PATENT RIGHT, DDS shall have the right to take over the
      prosecution and maintenance of such DDS IONTOPHORETIC PATENT RIGHTS,
      which rights shall no longer form a part of and be covered by the
      licenses granted by DDS pursuant to this Agreement.

3.    IOMED and DDS shall promptly inform the other in writing of any alleged
      infringement of which it shall become aware by a third party of any
      patents within the DDS IONTOPHORETIC PATENT RIGHTS and provide such other
      with any available evidence of infringement.

4.    During the TERM and the ADDITIONAL TERM, IOMED shall have the right to
      pursue at its own expense and for its own benefit any such infringements
      of the DDS IONTOPHORETIC PATENT RIGHTS and/or the IOMED PATENT RIGHTS.
      DDS shall agree to be named as a necessary party in an action brought by
      and fully financed by IOMED and will reasonably co-operate with such
      action. Any expenses borne by DDS shall be reimbursed by IOMED. Any
      recovery remaining after the deduction by IOMED of the reasonable expenses
      (including attorney's fees and expenses) incurred in relation to such an
      infringement proceeding shall constitute NET REVENUES for the purpose of
      this Agreement. Should IOMED decide not to pursue such infringers of the
      DDS IONTOPHORETIC PATENT RIGHTS, DDS may do so at its expense and for its
      own benefit, and IOMED will reasonably co-operate with such action. Any
      expenses borne by IOMED in co-operating with such action shall be
      reimbursed by DDS.

      exploitation; if the Parties are unable to agree upon such joint
      determination within ninety (90) days of such notice from IOMED, either
      party shall have the right to have such matter arbitrated. Such
      arbitration shall be conducted before an independent experienced patent
      attorney reasonably selected by the Parties, or on such other basis as
      shall be mutually reasonably agreeable, pursuant to the provisions of
      Article IX Paragraph 14.

      business (each of whom shall be bound by IOMED's customary confidential
      disclosure agreements), who shall be informed of such confidentiality
      obligation and for whose breach the disclosing party shall be responsible.

1.2.  Subject to the provisions of Paragraph 1.1., any information, whether
      written or oral (oral information shall be reduced to writing within one
      month by the Party giving the oral information and the written form shall
      be furnished to the other Party) pertaining to the DDS IONTOPHORETIC

              disclosing Party's efforts to obtain any such order or other
              remedy.  If any such order or other remedy does not fully preclude

      IOMED may not assign (other than by operation of law in the event of an
      acquisition of IOMED. or a merger or similar transaction subject to the

      rights and obligations to an AFFILIATE. DDS may not assign to an
      unaffiliated third party (other than by operation of law in the event of
      an acquisition of DDS, or a merger or similar transaction) its rights
      under this Agreement without the prior written consent of IOMED, which may
      be withheld in IOMED's sole discretion.

3.    Certain Changes of Control.

      In the event that an OFFERING PARTY makes or signifies its intention of
      make a bona fide offer which would result in such a party owning, directly
      or indirectly, more than fifteen per cent (15%) of IOMED's voting stock,
      on a fully-diluted basis, or otherwise controlling the IOMED's Board of
      Directors, or otherwise obtains substantial contractual rights pursuant to
      an agreement with IOMED to the DDS IONTOPHORETIC PATENT RIGHTS (as
      reasonably determined by DDS) (each, a "Control Transaction"), IOMED shall
      (x) not accept such offer until it shall have complied with the remaining
      provisions of this Paragraph without DDS's consent (in its sole
      discretion) and (y) advise the appropriate OFFERING PARTY that, in lieu of
      IOMED accepting such offer, such OFFERING PARTY should make a separate
      offer with respect to that portion of IOMED"s business that relates to the
      FIELD, and not to the remaining potion of IOMED's business. DDS and/or
      ELAN shall have a period of thirty (30) days to conduct appropriate due
      diligence and to determine whether it desires to match an offer made by an
      OFFERING PARTY with respect to that portion of IOMED's business that
      relates to the FIELD, (including the same economic, payment and other
      terms); it being understood that IOMED shall make available to DDS and/or
      ELAN reasonable and sufficient information to enable DDS and/or ELAN to
      conduct such due diligence. 

      In the event that DDS and/or ELAN determines to make such offer, IOMED
      shall accept such offer and expeditiously consummate such transaction with
      DDS and/or ELAN. Notwithstanding the foregoing, in the event that an
      OFFERING PARTY consummates a Control Transaction without the consent of
      the IOMED's Board of Directors (as such Board is comprised at the time
      such transaction is first publicly announced or commenced)(including
      without limitation, in connection with a tender offer or offers or proxy
      solicitation), DDS shall have the right in its sole discretion, to
      terminate the licences granted by DDS pursuant to this Agreement, without
      payment or penalty to IOMED.

      arbitrator.  A disputed performance or suspended performances pending the
      resolution of the arbitration must be completed within thirty (30) days
      following the final decision of the arbitrators or such other reasonable
      period as the arbitrators determine in a written opinion.  Any arbitration
      subject to this Paragraph 14 shall be completed within one (1) year from
      the filing of notice of a request for such arbitration.  The arbitration
      proceedings and the decision shall not be made public without the joint
      consent of the Parties and each Party shall maintain the confidentiality
      of such proceedings and decision unless (a) otherwise permitted by the
      other Party or (b) otherwise required by the applicable law in which case
      the Provisions of Article IX Paragraph 1.2.4. shall be applicable. The
      Parties agree that the decision shall be the sole, exclusive and binding
      remedy between them regarding any and all disputes, controversies, claims
      and counterclaims presented to the arbitrators. Application may be made to
      any court having jurisdiction over the Party (or its assets) against whom
      the decision is rendered for a judicial recognition of the decision and an
      order of enforcement.

15.   Withholding

      Any income or other taxes which IOMED is required by law to pay or
      withhold on behalf of DDS with respect to royalties and any other moneys
      payable to DDS under this Agreement shall be deducted from the amount of
      such royalties and moneys due. IOMED shall furnish DDS with proof of such
      payments.  Any such tax required to be paid or withheld shall be an
      expense of and borne solely by DDS. IOMED shall promptly provide DDS with
      a certificate or other documentary evidence to enable DDS to support a
      claim for a refund or a foreign tax credit with respect to any such tax so
      withheld or deducted by IOMED. Both Parties will reasonably cooperate in
      completing and filing documents required under the provisions of any
      applicable tax treaty or under any other applicable law, in order to
      enable IOMED to make such payments to DDS without any deduction or
      withholding.

16.   Indemnity

16.1. DDS shall indemnify, defend and hold harmless IOMED from all actions,
      losses, claims, demands, damages, costs and liabilities (including
      reasonable attorneys' fees) to which IOMED is or may become subject
      insofar as they arise out of or are alleged or claimed to arise out of any
      breach by DDS of any of its obligations under this Agreement or warranties
      of DDS.

16.2. IOMED shall indemnify, defend and hold harmless DDS from all actions,
      losses, claims, demands, damages, costs and liabilities (including
      reasonable attorney's fees) to which DDS is or may become subject insofar
      as they arise out of or are alleged or claimed to arise out of any
      breach by IOMED of any of its obligations under this Agreement or
      warranties of IOMED. IOMED shall assume the sole and entire
      responsibility and shall indemnify and save harmless DDS from any and all
      claims, liabilities, expenses, including reasonable attorney's fees,
      responsibilities and damages by reason of any claim, proceedings, action,
      liability or injury arising out of any defect in the PRODUCTS, including
      the manufacture, transport, packaging, storage, handling, distribution,
      marketing or sale of the PRODUCTS by IOMED.


16.3. As a condition of obtaining an indemnity in the circumstances set out
      above, the Party seeking an indemnity shall.

                  
      16.3.1. fully and promptly notify the other Party of any claim or
              proceeding, or threatened claim or proceeding;

      16.3.2. permit the indemnifying Party to take full care and control of
              such claim or proceeding;

      16.3.3. assist in the investigation and defence of such claim or
              proceeding;

      16.3.4. not compromise or otherwise settle any such claim or proceeding
              without the prior written consent of the other Party, which
              consent shall not be unreasonably withheld; and

      16.3.5. take all reasonable steps to mitigate any loss or liability in
              respect of any such claim or proceeding.
<PAGE>   29

16.4. Notwithstanding anything to the contrary in this Agreement, DDS and IOMED
      shall not be liable to the other by reason of any representation or
      warranty, condition or other term or any duty of common law, or under the
      express terms of this Agreement, for any consequential or incidental loss
      or damage (whether for loss of profit or otherwise) and whether occasioned
      by the negligence of the respective Parties, their employees or agents or
      otherwise.

17.   Entire Agreement

17.1. This Agreement including its Appendices, together with the ELAN
      AGREEMENT, the Note Purchase and Warrant Agreement and Registration Rights
      Agreement being entered into between Elan International Services Limited,
      Elan International Management Limited and IOMED, the Promissory Note and
      Secured Promissory Note being issued by IOMED to Elan International
      Management Limited and the further documents referred to therein, each of
      which are being executed of even date herewith, set forth the entire
      agreement and understanding of the Parties with respect to the subject
      matter hereof, and supersedes all prior discussions, agreements and
      writings in relating thereto, including the letter of agreement of 31st
      March 1997.

17.2. The Parties agree that the obligations of IOMED to provide access to the
      NDAs pursuant to Article V Paragraph 1 to DDS shall be discharged if such
      access is provided to ELAN pursuant to the equivalent provisions of the
      ELAN AGREEMENT.

17.3. The Parties agree that the obligations of IOMED to furnish the
      documentation and information to DDS pursuant to the provisions of Article
      II Paragraph 7, shall be discharged by furnishing such documentation to
      ELAN pursuant to the equivalent provisions of the ELAN AGREEMENT.
<PAGE>   30




17.4. The Parties agree that the obligations of IOMED to obtain the prior
      written consent of IOMED pursuant to Article II Paragraphs 2.1. or 2.2.
      shall be satisfied by obtaining the consent of ELAN pursuant to the
      equivalent provisions of the ELAN AGREEMENT.

17.5. The Parties agree that DDS's right of access and audit in any particular
      calendar year pursuant to Article IV Paragraph 3.4. shall be exhausted if
      such rights are exercised by ELAN pursuant to the equivalent provisions of
      the ELAN AGREEMENT; provided that nothing in this Paragraph shall limit or
      restrict DDS's rights to seek an adjustment to the royalties payable,
      whether by agreement between the Parties or pursuant to arbitration.

17.6. The Parties agree that the obligations of IOMED to obtain the prior
      written consent of DDS pursuant to Article IX Paragraph 3 shall be
      satisfied by obtaining the consent of ELAN pursuant to the equivalent
      provisions of the ELAN AGREEMENT.  In addition the Parties agree that the
      right of DDS to exercise its rights to conduct appropriate due diligence
      and to make an offer as envisaged by Article IX Paragraph 3 shall be
      discharged by the exercise of such rights by ELAN pursuant to the
      equivalent provisions of the ELAN AGREEMENT.  In the event that an
      OFFERING PARTY consummates a Control Transaction (as defined in Article IX
      Paragraph 3) without the consent of the IOMED's Board of Directors (as
      such Board is comprised at the time such transaction is first publicly
      announced or commenced) (including without limitation, in connection with
      a tender offer or offers or proxy solicitation), and in the event that
      ELAN determines at its sole discretion that it shall not terminate the
      licenses granted by ELAN pursuant to the ELAN AGREEMENT, DDS shall be
      deemed to have elected not to have terminated the licenses granted by DDS
      pursuant to this Agreement.

18.   Counterparts

      This Agreement may be executed in two counterparts, each of which shall be
      deemed an original and which together shall constitute one instrument.

                                                                   EXHIBIT 10.10

NOTE: CERTAIN PORTIONS OF THE EXHIBIT HAVE BEEN OMITTED BASED UPON A REQUEST FOR
CONFIDENTIAL TREATMENT. THE OMITTED PORTIONS HAVE BEEN SEPARATELY FILED WITH THE
COMMISSION.

                               LICENSE AGREEMENT

     THIS AGREEMENT is made upon the 27th day of December, 1996 and shall be
effective as of January 1, 1997, by and between IOMED, INC., a Utah corporation
("Iomed"), and FILLAUER, INC., a Delaware corporation (the "Licensee").  Iomed
and the Licensee are referred to herein individually as a "Party," and
collectively as the "Parties".
                                   RECITALS:
     A. On the effective date of that certain Asset Acquisition Agreement
between the Parties, of even date herewith (the "Purchase Agreement"), the
Licensee has purchased from Iomed certain assets of Iomed's Motion Control
Division ("Motion Control").
     B. Iomed is the exclusive licensee or the owner of certain patented and
unpatented technology, trade secrets, trademarks and trade names which are
utilized by Motion Control in connection with its business of the manufacture
and sale of certain prosthetic devices (the "Business").
     C. The Purchase Agreement contemplates that Iomed will grant to the
Licensee an exclusive license to such technology, trademarks and trade names,
in order to permit the Licensee to continue to operate the Business.
     D. The Parties desire to enter into this Agreement in order to fulfill the
requirements of the Purchase Agreement.
                                   AGREEMENT:
     NOW, THEREFORE, in consideration of the foregoing Recitals and the
covenants and agreements set forth herein, together with other good and
valuable consideration, the receipt and sufficiency of which is hereby
acknowledged, the Parties agree as follows:

160812.1

<PAGE>   2

   
    

     1. LICENSES.
     (a) On the effective date of this Agreement, Iomed herewith grants to the
Licensee an exclusive world-wide, royalty bearing sublicense in and to the
rights of Iomed to utilize the United States Letters Patent identified on
Exhibit "A" hereto (which is incorporated herein by reference), for the use,
manufacture and sale of those prosthetic devices described on Exhibit "B"
hereto (which is incorporated herein by reference), as granted to Iomed by that
certain License Agreement, dated October 1, 1992 (the "University License"),
between Iomed and the University of Utah Research Foundation.  The United
States Letters Patent described on Exhibit "A" hereto are referred to herein as
the "University Patents," the products described on Exhibit "B" hereto,
together with any improvements or additions thereto developed by the Licensee
or its "Sublicensees" (as hereinafter defined) after the effective date of this
Agreement, are referred to herein as the "University Products," and the
sublicense granted by this paragraph 1(a) is referred to herein as the
"Sublicense."  The Sublicense shall be exclusive even as to Iomed; provided,
however, that the Licensee acknowledges that the University License reserves to
the University of Utah Research Foundation the right to utilize the University
Patents for educational and research purposes at the University of Utah.  In no
event shall any use of the University Patents by the University of Utah
Research Foundation be deemed or construed to constitute a breach of this
Agreement by Iomed.
     (b) On the effective date of this Agreement, Iomed grants to the Licensee
an exclusive, world-wide, fee-bearing license (the "License") in and to all
patented and unpatented technology, trademarks, tradenames, know-how and trade
secrets owned or licensed by Iomed and which have been employed by Motion
Control in its conduct of the

                                       2
160812.1

Business, for the purpose of enabling the Licensee to develop, manufacture,
market and sell those products described on Exhibit "C" hereto (which is
incorporated herein by reference), together with any improvements or additions
thereto developed by the Licensee or its Sublicensees after the date of this
Agreement (collectively the "Iomed Products").  Such Iomed technology (the
"Iomed Technology") is more particularly described on Exhibit "D" hereto, which
is incorporated herein by reference.  The License shall be exclusive even as to
Iomed.
     (c) Pursuant to the Sublicense and the License, the Licensee shall have
the right to grant further sublicenses in and to the University Patents and the
Iomed Technology to persons or entities owned by, or under common control with,
the Licensee (collectively "Sublicensees").  Otherwise, the Licensee may not
sublicense, sell, assign or transfer the Sublicense or the License without the
prior written consent of Iomed.  No Sublicensee shall have the right to further
sublicense its rights under either the University Patents or the Iomed
Technology.
     2. ROYALTY AND LICENSE FEE.
     (a) In consideration of the grant of the Sublicense, the Licensee shall pay
to Iomed an earned royalty of one and one-half percent (1.5%) (the "Royalty") of
all "Net Sales Proceeds (as hereinafter defined) received by the Licensee or its
Sublicensees from all sales of the University Products which are made between
the effective date of this Agreement and September 30, 2007 (the "Royalty
Period").  Following the Royalty Period, no royalties, fees or other payments
shall be due Iomed as the result of or in connection with the sale by the
Licensee or any of its Sublicensees, of the University Products or any

                                       3

other products which incorporate or utilize any of the technology which is the
subject of the University Patents or which is otherwise covered by the
Sublicense.
     (b) As consideration for the License, the Licensee shall pay to Iomed, in
lieu of any royalty or other payment, a license fee (the "License Fee") *****
************************************************************* received by the
Licensor, or its Sublicensees, from all sales of Iomed Products which are made
between the effective date of this Agreement and January 1, 2004 (the "Fee
Period").  Following the Fee Period, no license fee or other payment (other
than the Royalty specified in paragraph 2(a) hereof to the extent applicable)
shall be due or payable to Iomed by the Licensee or any of its Sublicensees as
a result of or in connection with the manufacture or sale of the Iomed Products
or any other product which incorporates any of the Iomed Technology.
     (c) As used in this Agreement, the term "Net Sales Proceeds" shall mean

the Licensee or by one of its Sublicensees to a person, firm or entity which is
owned or controlled by or is under common control with the Licensee or such
Sublicensee, then the Royalty or the License Fee, as appropriate, which shall
be due and payable to Iomed as the result of such sale shall be calculated on

*********.  Payment of the Royalty and License Fee shall be made within *******

Products sold by the Licensee or its Sublicensees during the ****************
in question, together with a statement as to the manner in which the Net Sales
Proceeds from such sales was calculated.
     (b) All Royalty and License Fee payments shall be made in United States

for the currency in question quoted by The Wall Street Journal on the last
business day of such calendar quarter.
     (c) Notwithstanding any provision of this Agreement to the contrary, in

records detailing the costs incurred by the Licensee or its Sublicensees in

sufficiently detailed to enable to Licensee to calculate, in accordance with
generally accepted accounting principles, the Net Sales Proceeds received by
the Licensee and the Sublicensees from their sale of the University Products
and the Iomed Products, and to determine the amount of the required Royalty and
License Fee payments.  Iomed shall have access to and the right, upon
reasonable notice, to inspect and audit such books and records in order to
verify the correctness of the Royalty and License Fees paid by the Licensee.
Any such audit shall be conducted by an accounting firm selected by Iomed.
     (b) If Iomed causes the books and records of the Licensee or of any of the
Sublicensees to be audited, and such audit establishes that the Licensee did
not pay to Iomed the full amount of the Royalty or License Fee actually due for
the period covered by such audit, the Licensee shall immediately pay to Iomed
all additional amounts due, plus interest thereon at the rate of *******
**********************************************************.  If such audit
establishes that the Licensee has underpaid the Royalty or License

160812.1

and hold Iomed harmless from and against, and hereby assumes liability for the
payment of, any loss, liability or damage and for all costs and expenses,
(including reasonable costs of investigation and reasonable attorneys,
accountants and expert witness fees) of whatever kind and type that may be
imposed upon, suffered or incurred by or asserted against Iomed as a
consequence of or in connection with any liability from or relating to the use
of the University Products or the Iomed Products by customers of the Licensee
or its Sublicensees, or by the ultimate end-users of such University Products
and Iomed Products.
     6. PATENT AND TRADEMARK MATTERS.
     (a) The Licensee shall diligently prosecute and maintain all of the
patents, trademarks and tradenames specified on Exhibits "A" and "D" hereto
(collectively, the "Patents and Marks") using counsel of its choice and at its
sole cost and expense.  If, for any reason, the Licensee elects to abandon the
prosecution, maintenance or reinstatement of any of the Patents and Marks, it
will promptly notify Iomed of such election and, in any event, shall provide
such notice in sufficient time to allow Iomed to comply with its obligations
under Article 9 of the University License.

     (b) If either Party learns that any claim or suit (an "Action") has been
made or brought for patent, trademark or other infringement as the result of
the manufacture or sale of the University Products or the Iomed Products, such
Party shall promptly notify the other Party of such action.  The Licensee shall
have the first right, but not the obligation, to defend and to control the
defense of such Action, at its expense.  Iomed will assist the Licensee,
without cost to the Licensee, in the defense of such Action by providing
information and fact witnesses to the extent reasonably available.  Iomed shall
have the right to be represented in such Action by its own legal counsel, at
its own expense, provided that such legal counsel will act only in an advisory
capacity.  If Licensee elects not to defend such claim, it shall so notify
Iomed, in writing, and Iomed shall, thereafter, have the right and option, but
not the obligation, to defend and control the defense of such Action or the
settlement thereof.
     (c) If either Party learns of any infringement of the Patents and Marks by
a third party, or of another improper or illegal use of the technology covered
by the Sublicense or the License, such Party shall promptly notify the other of
the alleged infringement, in writing.  The Licensee shall have the first right
to settle with or institute legal action against the alleged infringer.  Any
monies or other benefits which are recovered through such settlement or legal
action shall be retained by the Licensee.  If the Licensee does not initiate
settlement or legal action within 60 days after its receipt of notice of the
alleged infringement, then Iomed shall have the right to settle with or
institute legal action against the alleged infringer and to retain all monies
or other benefits which are recovered through such action.

     12. TERMINATION.
     (a) Licensee may, at its option, terminate this Agreement if any
representation or warranty of Iomed contained in this Agreement shall prove to

asserted within the survival period provided in paragraph 9 hereof, or if the
Licensee shall be in material breach of any of the other provisions of this
Agreement, including but not limited to its obligations to pay the Royalty and
the Licensee Fee in accordance with the provisions of paragraphs 2 and 3
hereof, which breach shall continue uncured for a period of 30 days after
written notice thereof by Iomed.
     (ii) If the Licensee shall be adjudicated bankrupt or insolvent by any
court of competent jurisdiction or shall be voluntarily or involuntarily placed
in reorganization under any bankruptcy law or shall make an assignment for the
benefit of creditors or shall consent to the appointment of a receiver,
liquidator or trustee for itself in any court whatsoever, seeking to take
advantage of any bankruptcy or insolvency act, or shall admit in writing its
inability to pay its debts as they mature.
     13. EFFECT OF TERMINATION.
     (a) Upon the termination of this Agreement, by either Party, pursuant to
the provisions of paragraph 12 hereof, any obligation which accrued prior to
the effective date of such termination shall continue in full force and effect
and shall not be terminated, reduced or otherwise altered as the result of or
in connection with such termination.  Additionally, the rights and obligations
of the Parties set forth in paragraphs 5, 10(b) and 14 hereof shall survive the
termination of this Agreement.
     (b) Upon the termination of this Agreement, by either Party, pursuant to
paragraph 12 hereof, the right of the Licensee and of its Sublicensees to
manufacture or sell the University Products, the Iomed Products or any other

the Sublicense or the License shall completely terminate.  Following such
termination the Licensee shall, upon the written request of

                                       13

Iomed, assign (and cause each Sublicensee to similarly assign) to Iomed all
improvements to the University Products and to the Iomed Products which are
developed by the Licensee and its Sublicensees after the effective date of this
Agreement.
     14. CONFIDENTIALITY.
     (a) The Licensee acknowledges that the Iomed Technology (the "Confidential
Information") constitutes the valuable, unique and proprietary asset of Iomed;
provided, however, that the term "Confidential Information", as used herein,
shall not include any information or data which (i) is in or becomes a part of
the public domain by any means other than the Licensee's breach of its
obligations hereunder or (ii) is rightfully known to the Licensee at the time
of disclosure by Iomed, as demonstrated by the contemporaneous written records
of the Licensee, or (iii) is, at any time, disclosed to the Licensee by a third
party who has received and disclosed such information without the breach of any
obligation of confidentiality to Iomed or to any third party.  For purposes of
this paragraph 14, information shall not be deemed to be part of the public
domain or within the Licensee's knowledge merely because it may be embraced in
a more general disclosure, or because it may be derived from combinations of
information generally available to the public or otherwise within the
Licensee's knowledge.
     (b) The Licensee shall maintain all of the Confidential Information in
confidence and shall not, except as specifically permitted herein, disclose the
same to any third party (including without limitation affiliates of the
Licensee who are not Sublicensees) unless required to do so by court order or
by law, in which case the Licensee shall notify Iomed, in writing, prior to
making such disclosure and shall cooperate with Iomed to preserve and protect
the confidentiality of the Confidential Information to the fullest extent

                                       14

possible.  The Confidential Information may be disclosed by the Licensee to
those of its employees who need to know the same in order to enable the
Licensee to utilize the Sublicense and the License, and to its permitted
Sublicensees; provided that each such person and entity is advised of the
obligations of confidentiality contained herein.  Any breach of the provisions
of this Paragraph 14(b) by such employees or Sublicensees shall be deemed, for
all purposes, to constitute a breach hereof by the Licensee.
     15. RELATIONSHIP OF THE PARTIES.  This Agreement shall not be deemed or
construed to create between Iomed and the Licensee the relationship of
principal and agent, joint venturers, co-partners, employer or employee, master
or servant, or any other similar relationship.  Neither Party shall have the
right or authority to bind or to act for or on behalf of the other Party.
Additionally, neither Party shall be liable to any third party, in any way, for
any engagement, obligation, contract, representation or transaction, or for any
negligent act or omission to act of the other Party, except as otherwise
specifically provided in this Agreement.
     16. NOTICES.  All notices, requests, consents, approvals and other

     17. REMEDIES.  Should default occur in the performance of any obligation
set forth in this Agreement, the non-defaulting Party shall be entitled to
obtain an injunction compelling the specific performance of the obligations of
this Agreement, in addition to any action for damages or for other relief as
may be available to the non-defaulting Party at law or in equity.  The
defaulting Party shall, in addition to any damages which may result from such
default, pay to the non-defaulting Party the costs, including reasonable
attorneys' fees, incurred by the non-defaulting Party in causing the cure of
such default or in otherwise enforcing its rights under this Agreement.
     18. WAIVER.  Any waiver by either Party of a breach of any term or
condition of this Agreement shall not constitute a waiver of any subsequent
breach of the same or any other term or condition of this Agreement.
     19. ENTIRE AGREEMENT.  With the exception of the Purchase Agreement and
the agreements contemplated thereby, this Agreement constitutes the entire
agreement and understanding between the Parties in regard to the subject matter

and governed by, the laws of the State of Utah, without giving effect to the
choice of law rules thereof.

Sublicense, as provided in this Agreement, with the United States Patent
Office, and Iomed shall execute and deliver such documents as may be reasonably
necessary to effect such recordation.
     22. COUNTERPARTS.  This Agreement may be executed in any number of
counterparts, each of which shall be deemed an original, but all of which shall
constitute one and the same instrument.
     IN WITNESS WHEREOF, the Parties have caused this License Agreement to be
executed by their duly authorized representatives as of the date first herein
written.
